DETAILED DESCRIPTION

In some embodiments, low power devices utilize encryption methods for secure communication. For example, low power encryption is able to involve a key exchange which includes sending and receiving keys. In some embodiments, the key exchange includes sending, receiving and generating random numbers, wherein the keys and random numbers are utilized to solve the equations.

To minimize power usage, instead of performing authentication (e.g., a key exchange) for every packet, the windowing is able to be pushed out. For example, there is a key exchange once every nth packet (e.g., n=50) instead of every packet. The number of packets between each key exchange is able to be any number, while recognizing that the farther apart the key exchange, the less power usage but also a slight decrease in security. In some embodiments, a device is only awake for a short period of time and sleeps for a majority of the time. Additionally, a device is able to turn off as many components as possible that utilize power, and then the device is able to turn on the components when needed.

In some embodiments, an extension of the Bluetooth® protocol is implemented. The Bluetooth® protocol includes sending a signal 2-ways. A first signal is sent from a low power device (e.g., IoT device), and then a signal is sent to the low power device (e.g., received from the sending device). After the low power device sends a signal (e.g., a beacon or other one-way transmission), the low power device listens for a short window/amount of time, and then goes to sleep to conserve power. Therefore, the low power device is asleep for approximately 99.9% of the time. During the short window, it may receive a 3-way handshake (e.g., perform the key exchange).

FIG. 1 illustrates a flowchart of a method of implementing low power encryption in motion according to some embodiments. In the step 100, a matrix-based communication is implemented between a low power device and another device. In some embodiments, the matrix-based communication includes a matrix-based key exchange. In some embodiments, the communication is not matrix-based; rather, another form of communication occurs between the low power device and another device. The low power device is able to be an IoT device and/or any other device which utilizes minimal power. For example, the low power device includes a battery which is charged initially and then is not charged again for many months or self-charges using ambient light and/or signals/waves. In another example, the low power device is powered by a battery or by collecting energy such as WiFi, kinetic vibrations or other ambient sources. The device communicating with the low power device is able to be any device such as a server, a user device, a backend device, or another IoT device. Included with or in addition to the matrix-based communication/key exchange is a message. For example, the low power device and the other device send messages including requests and/status information.

As described herein, the matrix-based communication involves real numbers and matrices. Secret information, X, is able to be sent with random number Y (e.g., X+Y) from a first device (e.g., Person A) to a second device (e.g., Person B). Then, a response is sent back from the second device to the first device, another random number Z is included but the secret information, X, is not included in the response, so instead of X+Y+Z, the response is just Y+Z. This is performed using matrices.

$A=❘\begin{array}{cc}{a}_1& a_2\\ a_3& a_4\end{array}❘X_i=❘\begin{array}{cc}{x}_1& x_2\\ x_3& \frac{x_2{x}_3}{x_1}\end{array}❘$

• • A·X=M, where M is a matrix.
  • A=X⁻¹M.
  • X is solvable if one knows A and M, but A is not solvable just by knowing X and M.For example, if Person A sends a message M to Person B and to Person C, where person B has information A and Person C has information M, then Person B has enough information to determine the message, but Person C does not.

Person A sends a function of matrix A and message X (e.g., F (A, X)) to Person B. Message 1 (M₁) equals the function, F(A, X). Person B returns back Message 2, M₂=F(A, X, B), where B is Matrix B. Person A removes matrix A, and sends Message 3, M₃=F(X, B), so that Person B receives the message X. In some embodiments, many more matrices (e.g., 8 or more matrices), more multiplications, and non-linear equations are utilized. Real numbers are utilized instead of integer numbers. Additionally, even if one were to determine Matrices A and B, the equation to solve for X is a diophantine 4^th order equation. Therefore, it is not solvable using an algorithmic approach, so brute force must be utilized, which means even a quantum computer would still take many years to decrypt a sufficiently encrypted message.

An authentication system is paired with the matrix-based encryption to ensure security. In the example of Person A exchanging a message X with person B, there is a three way key exchange. Random information (Matrix G) is added to the message, and Matrix G makes no sense even with a brute force attack. Additionally, Person A has his own authentication Matrix N₁, and Person B has his own authentication Matrix N₂. An authentication system is implemented which utilizes N₂·N₁⁻¹. Additionally, G is included with N₁ and N₂, so that if a third party attempts to access the information, they receive white noise. In some embodiments, the matrix-based encryption is utilized with RSA and/or ECC to perform quantum tunneling. Even if there is a virus on a device, since the virus is not registered on the authentication system, the virus will receive white noise when trying to access information.

In the step 102, a specified number of messages/packets are sent between the low power device and the other device without performing an authentication communication (e.g., a key exchange). For example, 50 packets are sent before the next matrix-based key exchange. A counter is able to be utilized to determine when to perform the next matrix-based messaging/key exchange. In some embodiments, a clock is utilized to determine when to perform the next matrix-based messaging/key exchange.

In some embodiments, fewer or additional steps are implemented. In some embodiments, the order of the steps is modified.

FIG. 2 illustrates a flowchart of another method of implementing low power encryption in motion according to some embodiments. In the step 200, a low power device sends a communication (e.g., signal) to another device. In some embodiments, the communication is a matrix-based communication as described herein.

In the step 202, the low power device waits and listens for a very short period of time (e.g., 1 second, 5 seconds, 5 minutes). While waiting and listening, the low power device is using power (e.g., to power the receiver).

In the step 204, if a communication is received during the listening window, the low power device takes an action. For example, the low power device and the other device may perform the matrix-based key exchange described herein. In another example, the low power device may be a sensor, and if another device sends a status request, the low power device may respond with status information after the matrix-based key exchange.

In the step 206, the low power device goes into sleep mode to conserve power. After the awake period or after an action is taken, the low power device enters sleep mode. The process repeats after a while by going back to step 200. For example, the low power device uses its internal clock or other mechanism to determine when to wake up and send another communication. By being in sleep most of the time (e.g., 99.9% of the time), the low power device significantly reduces its power consumption. In some embodiments, fewer or additional steps are implemented. For example, a low power device is configured and implemented to utilize less power such as by turning off certain components when not in use and by utilizing special sensors and power capturing/charging components configured to charge the low power device's battery. In some embodiments, the order of the steps is modified.

In some embodiments, the low power encryption in motion methods are utilized together. For example, the low power device sends a signal and waits/listens for a response during a short window, but only every nth window is there a key exchange. In this case since the window occurs infrequently, the nth window may be a lower number such as every 10^th time, although any number could be specified.

Key Exchange with Small Encrypted Payload

In some embodiments, low power devices utilize the matrix encryption methods described herein for encryption. Low power devices typically cannot send/receive large amounts of data since sending/receiving more data uses more power.

A communication device sends a signal/message (e.g., beacon) to a low power device (e.g., IoT device, credit card). In addition to or included with the message, the communication device is able to send a small amount of data (e.g., 20 bytes). For example, the message as a total (including keys, equations) is 20 bytes or fewer, or the message has a size limit, and the additional information (e.g., keys, equations) has a different size limit (e.g., 20 bytes). In some embodiments, the communication comprises a payload as small as 20 bytes or fewer. The payload size is able to be modified depending on a specification such as a Power Specification. There are multiple keys (e.g., k₁, k₂) at the communication device and multiple keys (e.g., k₁, k₂) at the low power device. The communication device and the low power device each have real number random number generators. Using the random number generators, one or more random numbers between 0 and 1 are able to be generated. Each random number is 4 bytes, so for 2 random numbers, there is a total of 8 bytes used. The following shows exemplary equations:

$r_1\left(1-k_1\right)+r_2{k}_1=m_1{r}_1\left(1-k_2\right)+r_2{k}_2=m_2{r}_1\left(1-x\right)+r_{2}x=m_{3}x=\frac{\left[m_3-r_1\right]}{r_2-r_1}$

• • where x is the message;
  • k₁ and k₂ are keys;
  • r₁ and r₂ are randomly generated numbers; and
  • m₁, m₂ and m₃ are real numbers between 0 and 1 calculated using the keys and randomly generated numbers. Additionally, m₁, m₂ and m₃ are functionally unrelated, such that if someone snoops and retrieves the values of m₁, m₂ and m₃, the snooper retrieves garbage data or white noise even if x is constant.

For example, the communication device sends the equations for m₁ and m₂, which are each 4 bytes, to the low power device. The communication device also sends the message or the equation for m 3 (which includes the message) which is also 4 bytes (meaning a total of 12 bytes for the 3 equations). The variables r₁ and r₂ are unknown by any third party. The variables r₁ and r₂ are then able to be determined/calculated by the low power device. In some embodiments, r₁ and r₂ are received by the low power device. The value/information of x (the message) is able to be decrypted by the low power device using r₁ and r₂ and the equations.

FIG. 3 illustrates a flowchart of a method of implementing low power encryption in motion according to some embodiments. In the step 300, a communication is sent from a communication device to a low power device (or vice versa). The communication includes an encrypted message. In some embodiments, the communication includes a plurality of equations. In some embodiments, the communication is limited in size (e.g., less than 20 bytes). The communication includes information that changes each communication such as a session identification number, a date/time stamp, and/or any other information to prevent a third party from capturing/copying a communication and sending the captured transmission. For example, the communication includes an identifier which counts up (e.g., for every package or is time-based), so that if the identifier is the same as or below a previous identifier, then the device knows that the communication is a duplicate, and is able to reject the communication and/or not respond.

In the step 302, random numbers within the plurality of equations are determined or acquired by the low power device. The random numbers are real numbers between 0 and 1, although other real numbers are able to be used. In some embodiments, the random numbers are received via the communication. In some embodiments, the random numbers are generated based on the communication using the random number generator on the low power device.

In the step 304, a message within the communication is decrypted. In some embodiments, the decryption is based on the random numbers and the equations as described herein. In some embodiments, fewer or additional steps are implemented. For example, the communication is able to be implemented without random numbers. In some embodiments, the order of the steps is modified.

FIG. 4 illustrates a diagram of a low power device in a communication system according to some embodiments. The low power device 400 includes a transmitter/receiver 402 (e.g., an antenna) to receive communications. The low power device 400 is also able to include other components 404 such as a battery (e.g., Lithium ion), one or more sensors, a processing unit, memory (e.g., RAM), one or more charging components (e.g., a small photovoltaic cell, a vibration converter) and other computing components. The one or more charging components are able to charge the battery using very small amounts of energy from energy sources such as ambient light, tiny vibrations, or wireless signals. The battery (along with the charging components) are configured such that the battery is able to be charged once and then maintain that charge for many months. The low power device 400 is able to send/receive a communication (e.g., one-way communication/data stream/beacon) as described herein. In some embodiments, the low power device 400 sends a communication periodically (e.g., once every 20 minutes). The communication is able to be RF, infrared, WiFi, Bluetooth, 5G (xG), or any other wireless communication. The low power device 400 is able to communicate with any device 410 (e.g., a mobile device, a server, another IoT device). In some embodiments, the low power device 400 includes fewer or additional components.

Encryption for One-way Data Stream

In some embodiments, encryption for a one-way data stream is implemented. In some embodiments, as a device is provisioned, the two-way exchange (e.g., two handshakes) with a second device is able to be implemented. Then, since the two-way exchange with the second device has already occurred, the device is able to send one-way data streams to the second device. The one-way data stream is able to be a broadcast, cyphereye data, Bluetooth®, stream, coordinate information, and/or any other data.

FIG. 5 illustrates a diagram of a one-way data stream encryption according to some embodiments. In the step 500, a two-way exchange (pre-registration) occurs between two devices (e.g., client and server). For example, the matrix-based exchange described herein occurs between a first device and a second device. After the two-way exchange is performed, a device is able to send an encrypted one-way data stream to the second device, in the step 502. Since the pre-registration has established authentication/encryption credentials/information between the devices, the encrypted one-way data stream is able to be decrypted by the second device, while being securely transmitted. In some embodiments, the one-way data steam is from a mobile device, server, or other device to an Internet of Things device (or vice versa). In some embodiments, the one-way data stream is status information (e.g., status of a sensor chip to a central station). In some embodiments, the one-way-data stream includes instructions (e.g., from a central device to an IoT device to perform a specific type of monitoring or to go into a certain state/mode such as to go to sleep). In some embodiments, fewer or additional steps are implemented. In some embodiments, the order of the steps is modified.

Dynamic Key Exchange for Moving Target

In some embodiments, a dynamic, key exchange for a moving target is implemented. For example, a client (e.g., mobile device, autonomous vehicle) is moving and keeps switching between servers/receivers (e.g., devices positioned on light/telephone poles). In some embodiments, the key exchange is matrix-based. In some embodiments, a dynamic key exchange registration is implemented where each time the signal drops at one receiver, the device connects with another receiver and performs another key exchange. In some embodiments, the device and/or receivers are pre-registered with an authentication server. In some embodiments, the device and/or receivers are registered (or pre-registered) with an authorization server, where the authorization server performs the processing and is able to send a decrypted message (based on an encrypted message from a receiver) to the device which forwards the message to another receiver (e.g., the server on the light pole), or the decrypted message is based on an encrypted message from a device, and the decrypted message is sent to the receiver. The receivers are able to send a one-way data stream (e.g., beacon) to the moving device (or vice versa). In some embodiments, the device and/or receivers send a matrix-based encrypted communication to the receiver/device which forwards the communication to the authentication server which performs the decryption.

FIG. 6 illustrates a flowchart of a method of performing a dynamic key exchange for a moving target according to some embodiments. In the step 600, a device is pre-registered with an authentication server. For example, the pre-registration described herein is implemented. In another example, pre-registration includes storing/recording device information (e.g., MAC address or other identification information) at the authentication server, so that the authentication server already “knows” the device. In some embodiments, other matrix-based encryption information is utilized for pre-registration. Similarly, the receiver is able to be pre-registered or registered with the authentication server. A pre-registered key or a dynamically-generated key is able to be used with the secure key exchange.

In the step 602, the device communicates with a receiver. The communication is able to include a communication from the device to the receiver, a communication from the receiver to the device, or a combination thereof. Initially, a dynamic, key exchange between the device and the receiver is implemented as described herein. In some embodiments, each time the device switches to a new receiver, the dynamic key exchange is performed again. In some embodiments, the authentication server is able to assist with the dynamic key exchange between the device and the receiver. For example, the authentication server assists with the authentication by performing the key exchange computations and then provides the result to the device and/or the receiver. In another example, the authentication sever is able to perform the authentication with the device and/or the receivers such that the key exchange does not occur each time the device switches to a new receiver. In another example, the authentication server is able to store data to expedite the dynamic key exchange between the device and the receivers. Furthering the last example, if a device and/or receiver is verified or “known” by the authentication server, the authentication process/dynamic key exchange is able to be skipped or expedited. In some embodiments, the receiver forwards dynamic key information received from the device to the authentication server, and the authentication server performs the key analysis (e.g., matrix multiplication) to provide authentication data to the receiver and/or the device. Furthering the example, the device sends an encrypted communication to the receiver, but the receiver does not decrypt the communication; the receiver forwards the encrypted communication to the authentication server which performs the decryption, and then takes another action such as returning the decrypted message to the receiver. After the device and/or receiver perform the dynamic key exchange, the message and/or messages are able to be acted upon. For example, if the dynamic key exchange accompanies a status request, a receiver is able to send a message back to the device with the status of the receiver. In another example, the messages to the receiver are able to include commands for the receiver to take a specified action. Similarly, the receiver is able to send commands to the device, and the device will take a specified action.

In the step 604, the device determines whether to switch to another receiver. Determining when and whether to switch to another receiver is able to be implemented in any manner such as detecting that an ACK has not been received in response to a communication with the receiver, detecting a low signal strength from a receiver, utilizing a zone mapping which indicates which receiver services which zone, and/or any other manner. In some embodiments, when the device determines to switch to another receiver, the process resumes at the step 602 to perform an authentication such as a dynamic key exchange. In some embodiments, the device does not determine whether to switch to a new receiver, and instead, the device broadcasts a communication, and whatever receiver is nearby receives the communication. The communication is encrypted as described herein, so receiver that receives the communication will still perform decryption. Similarly, the device is able to receive a communication from whichever receiver is nearby. In some embodiments, fewer or additional steps are implemented. In some embodiments, the order of the steps is modified.

FIG. 7 illustrates a diagram of a system for implementing a dynamic key exchange for a moving target according to some embodiments. A device 700 communicates with a set of receivers 702. The device 700 is able to be any device such as a mobile phone, an autonomous vehicle, an IoT device, a server or others. The receivers 702 are able to be any device such as a mobile phone, an autonomous vehicle, a server, an IoT device, or others. An authentication server 704 is able to be used to authenticate (or pre-authenticate) the device 700 and/or the receivers 702. In some embodiments, the authentication server 704 is able to be used to authenticate (or pre-authenticate) the communication to/from the device 700. In some embodiments, the device 700 is able to communicate with the authentication server 704, and/or the set of receivers 702 are able to communicate with the authentication server 704. The communication between each of the devices (e.g., device 700, receivers 702 and authentication server 704) is able to be any implementation such as WiFi, cellular, 5G/xG, Bluetooth, and/or any combination thereof. The authentication server 704 is able to be located anywhere such as at a central location.

In some embodiments, the device 700 and/or the set of receivers 702 are pre-registered with an authentication server 704. Any form of pre-registration is able to be implemented. While the device 700 is moving, the device 700 will connect/communicate with several of the set of receivers 702. The communication between the device 700 and the set of receivers 702 is secure. In some embodiments, the key exchange is implemented each time the device 700 connects with a receiver 702. In some embodiments, the authentication sever 704 performs the key exchange by receiving the communication and accompanying matrix/encryption information, and provides access for the receiver 702. For example, the device 700 attempts to connect with a receiver 702, so the key exchange is implemented. The receiver 702 passes the information to the authentication server 704, which performs the processing (e.g., matrix multiplication), and provides the key information back to the receiver 702 and/or the device 700, so that the device 700 and the receiver 702 are able to communicate. In some embodiments, the authentication server 704 is able to use the pre-registration information to bypass security protocols and/or to be utilized with the key exchange. As the device 700 moves and leaves range/signal of the receiver, the device 700 communicates with another receiver in the set of receivers 702. The key exchange occurs with the other receiver, and so on with additional receivers. As described herein, determining when to switch to another receiver is able to be performed in any manner such as by detecting when a signal, quality of service, and/or speed of another receiver is higher than the current receiver, detecting when a distance of another receiver is lower than the current receiver, and others.
