Further, processing time is reduced by performing the basic authentication before the API Key authentication.
Referring to
At step S201, basic authentication is performed. A service request for authentication is received at the API gateway 220 from a user/client 210. The basic authentication is an individual authentication. For example, the service request may include a basic credential, which may include a username and/or password. The basic credential is sent from the API gateway 220 to a centralized tool (e.g., identity management (IDM)/identity and access management (IAM)). The IDM/IAM tool 230 determines whether the basic credential is authorized and sends a response back to the API Gateway 220 based on the authorization result. At step S202, if there is no basic authentication, then the gateway error response handler 270 will block the service request and send a message to the user 210 indicating that the request is unauthenticated (e.g., step S210). If the basic authentication is validated at step S202, then it is determined at step S203 whether there is a valid API Key. If there is not a valid API Key then the gateway error response handler 270 will block the service request and send a message to the user 210 indicating that the request is unauthenticated (e.g., step S210).
At step S204 it is determined whether the API Key is expired. If it is expired then the gateway error response handler 270 will block the service request and send a message to the user 210 indicating that the request is unauthenticated (e.g., step S210). If the API Key is not expired, at step S205, the API Key subscription is checked. If there is no API Key subscription, then the gateway error response handler 270 will send an unauthenticated message to the user 210 (e.g., step S210). If there is an available API Key subscription (S206-Yes), then a service request is sent to a backend service (e.g., step S207). The backend service may be an application and/or a microservice, but is not limited to this. After processing the service request, at operation S208, the backend service sends a service response to the API gateway 220. At operation S209, the API gateway 220 forwards the service response to the client application 210.
At step S221, it is determined whether there is a basic credential for basic authentication stored in the basic authentication cache. For example, before an authentication is sent to the IDM/IAM tool 230, the cache may be searched. If the authentication result is retrieved in the cache, the API Key authentication may be performed. If the result is not found in the cache, the IDM tool will be checked, in accordance with step S201 of
Next, at step S223, the API Key cache may be searched to determine whether the API Key cache includes the authentication. If no authentication is found, then at step S224, API Key validation is performed. If the API Key authentication result is found in the cache, then the request is authenticated (e.g., step S225). According to an embodiment, once the API Key is validated, the process is similar to operation S206 in
Referring to
According to an embodiment, if the basic authentication information is determined to be valid, then the API Key authentication information is sent to the API Key Manager 340 (e.g., step S307). According to an embodiment, the API Key credential may be a string of characters and numbers. According to an embodiment, the API Key is generated by the gateway. According to an embodiment, the gateway uses the client's information to generate the API Key. The API
Key Manager 340 receives the API Key authentication information, determines whether the API Key authentication information is valid, and the API Key manager 340 returns a result of the API Key validation to the gateway 320 (e.g., step S308). If the API Key is not validated, then the service request is blocked and a message is sent to the user 310 indicating that the request is unauthenticated (e.g., step S310).
If the API Key authentication information is validated, then the gateway 320 will forward the service request to backend service 350 (e.g., step S312). The backend service may be an application and/or a microservice, but is not limited to this. At step S313, a service response is forwarded to gateway 320, which is then forwarded from the gateway 320 to the client 310 at step S314.

For example, user device 410 may include a computing device (e.g., a desktop computer, a laptop computer, a tablet computer, a handheld computer, a smart speaker, a server, etc.), a mobile phone (e.g., a smart phone, a radiotelephone, etc.), a wearable device (e.g., a pair of smart glasses or a smart watch), or a similar device. In some implementations, user device 410 may receive information from and/or transmit information to platform 420.
Platform 420 includes one or more devices capable of receiving, generating, storing, processing, and/or providing information. In some implementations, platform 420 may include a cloud server or a group of cloud servers. In some implementations, platform 420 may be designed to be modular such that certain software components may be swapped in or out depending on a particular need. As such, platform 420 may be easily and/or quickly reconfigured for different uses.
In some implementations, as shown, platform 420 may be hosted in cloud computing environment 422. Notably, while implementations described herein describe platform 420 as being hosted in cloud computing environment 422, in some implementations, platform 420 may not be cloud-based (i.e., may be implemented outside of a cloud computing environment) or may be partially cloud-based.
Cloud computing environment 422 includes an environment that hosts platform 420. Cloud computing environment 422 may provide computation, software, data access, storage, etc., services that do not require end-user (e.g., user device 410) knowledge of a physical location and configuration of system(s) and/or device(s) that hosts platform 420. As shown, cloud computing environment 422 may include a group of computing resources 424 (referred to collectively as “computing resources 424” and individually as “computing resource 424”).
Computing resource 424 includes one or more personal computers, a cluster of computing devices, workstation computers, server devices, or other types of computation and/or communication devices. In some implementations, computing resource 424 may host platform 420. The cloud resources may include compute instances executing in computing resource 424, storage devices provided in computing resource 424, data transfer devices provided by computing resource 424, etc. In some implementations, computing resource 424 may communicate with other computing resources 424 via wired connections, wireless connections, or a combination of wired and wireless connections.
As further shown in
Application 424-1 includes one or more software applications that may be provided to or accessed by user device 410. Application 424-1 may eliminate a need to install and execute the software applications on user device 410. For example, application 424-1 may include software associated with platform 420 and/or any other software capable of being provided via cloud computing environment 422. In some implementations, one application 424-1 may send/receive information to/from one or more other applications 424-1, via virtual machine 424-2.
Virtual machine 424-2 includes a software implementation of a machine (e.g., a computer) that executes programs like a physical machine. Virtual machine 424-2 may be either a system virtual machine or a process virtual machine, depending upon use and degree of correspondence to any real machine by virtual machine 424-2. A system virtual machine may provide a complete system platform that supports execution of a complete operating system (“OS”). A process virtual machine may execute a single program, and may support a single process. In some implementations, virtual machine 424-2 may execute on behalf of a user (e.g., user device 410), and may manage infrastructure of cloud computing environment 422, such as data management, synchronization, or long-duration data transfers.
Virtualized storage 424-3 includes one or more storage systems and/or one or more devices that use virtualization techniques within the storage systems or devices of computing resource 424. In some implementations, within the context of a storage system, types of virtualizations may include block virtualization and file virtualization. Block virtualization may refer to abstraction (or separation) of logical storage from physical storage so that the storage system may be accessed without regard to physical storage or heterogeneous structure. The separation may permit administrators of the storage system flexibility in how the administrators manage storage for end users. File virtualization may eliminate dependencies between data accessed at a file level and a location where files are physically stored. This may enable optimization of storage use, server consolidation, and/or performance of non-disruptive file migrations.
Hypervisor 424-4 may provide hardware virtualization techniques that allow multiple operating systems (e.g., “guest operating systems”) to execute concurrently on a host computer, such as computing resource 424. Hypervisor 424-4 may present a virtual operating platform to the guest operating systems, and may manage the execution of the guest operating systems. Multiple instances of a variety of operating systems may share virtualized hardware resources.
Network 430 includes one or more wired and/or wireless networks. For example, network 430 may include a cellular network (e.g., a fifth generation (5G) network, a long-term evolution (LTE) network, a third generation (3G) network, a code division multiple access (CDMA) network, etc.), a public land mobile network (PLMN), a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a telephone network (e.g., the Public Switched Telephone Network (PSTN)), a private network, an ad hoc network, an intranet, the Internet, a fiber optic-based network, or the like, and/or a combination of these or other types of networks.

The number and arrangement of components shown in
In embodiments, any one of the operations or processes of
According to example embodiments, a basic authentication is combined with API Key authentication. With only basic authentication that is not combined with API Key authentication, once a user is authorized using basic authentication, the user is able to access all APIs, programs, data, etc., available under basic authentication. However, by combining basic authentication and API Key authentication, the user may be restricted from accessing specific APIS, programs, data, etc. As a result, security is increased by requiring both basic authentication and API Key authentication. Further, as a result of combining basic authentication and API Key authentication, API throttling on a client level may be performed.
The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the implementations to the precise form disclosed. Modifications and variations are possible in light of the above disclosure or may be acquired from practice of the implementations.
Some embodiments may relate to a system, a method, and/or a computer readable medium at any possible technical detail level of integration. Further, one or more of the above components described above may be implemented as instructions stored on a computer readable medium and executable by at least one processor (and/or may include at least one processor). The computer readable medium may include a computer-readable non-transitory storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out operations.
