Claims
- 1. A method of transmitting information signals to a first device over a communications network, the information signals transmitted from a secure telephone device coupled between a telephone base and telephone microphone, the secure telephone device having a keypad, the first device having a cryptographic system, the method of comprising the steps of:
- transmitting first signals to establish in the network a clear communication path between the secure telephone device and the first device;
- transmitting second signals from the secure telephone device to the cryptographic system of the first device, the second signals for use in converting the clear communication path to a secure communication path;
- generating information signals with use of the keypad of the secure telephone device; and
- transmitting the information signals from the secure telephone device to the first device over the secure network communication path.
- 2. The method of claim 1 wherein the second signals comprise a signal initiating the conversion of the clear communication path to a secure communication path.
- 3. The method of claim 1 wherein the second signals comprise signals reflecting a cryptographic key.
- 4. The method of claim 1 wherein the information signals comprise user identification signals.
- 5. The method of claim 4 wherein the user identification signals comprise a personal identification number.
- 6. The method of claim 4 wherein the user identification signals comprise a social security number.
- 7. A method of receiving information signals by a first device, the first device having a cryptographic system, the information transmitted by a telephone having a telephone microphone and a telephone base and a secure telephone device coupled between the microphone and base, the first device coupled to the telephone by a clear communications path of a network, the method comprising the steps of:
- transmitting first signals from the cryptographic system of the first device to the secure telephone device, the first signals for use in converting the clear communications path to a secure communications path; and
- receiving transmitted information signals from the secure communications path, the information signals transmitted by the secure telephone device.
- 8. The method of claim 7 wherein the secure telephone device includes a keypad and wherein the information signals are generated with use of the keypad.
- 9. A method of leaving a secure message for a recipient on a voice messaging system, the message transmitted from a telephone over a communications network to the voice messaging system, the telephone including a telephone base and microphone and having a secure telephone device coupled between the base and microphone, the voice messaging system having a cryptographic system, the method comprising the steps of:
- transmitting first signals from the telephone to establish in the network a clear communication path between the secure telephone device and the voice messaging system;
- transmitting second signals from the secure telephone device to the cryptographic system of the voice messaging system, the second signals for use in converting the clear communication path to a secure communication path; and
- transmitting a voice message from the telephone to the voice messaging system over the secure network path, the voice message for recording by the voice messaging system.
- 10. The method of claim 9 wherein the second signals comprise a signal initiating the conversion of the clear communication path to a secure communication path.
- 11. The method of claim 9 wherein the second signals comprise signals reflecting a cryptographic key.
- 12. A method of receiving a voice message at a voice messaging system, the voice messaging system having a cryptographic system, the voice message transmitted from a telephone having a microphone, a telephone base, and a secure telephone device coupled between the microphone and the base, the voice messaging system coupled to the telephone by a clear communications path of a network, the method comprising the steps of:
- transmitting first signals for the cryptographic system of the voice messaging system to the secure telephone device, the first signals for use in converting the clear communications path to a secure communications path; and
- receiving transmitted voice message signals from the secure communications path for recording by the voice messaging system, the voice message signals transmitted by the telephone.
- 13. A method of receiving a secure voice message from a voice messaging system, the message transmitted from the voice messaging system to a telephone over a communications network, the telephone including a telephone base and speaker and having a secure telephone device coupled between the base and speaker, the voice messaging system having an associated cryptographic system, the method comprising the steps of:
- transmitting first signals from the telephone to establish in the network a clear communication path between the telephone and the voice messaging system;
- transmitting second signals from the secure telephone device to the cryptographic system of the voice messaging system, the second signals for use in converting the clear communication path to a secure communication path; and
- receiving at the telephone the voice message transmitted from the voice messaging system over the secure communications path.
- 14. The method of claim 13 wherein the second signals comprise a signal initiating the conversion of the clear communication path to a secure communication path.
- 15. The method of claim 13 wherein the second signals comprise signals reflecting a cryptographic key.
- 16. A method for secure transmission of a recorded voice message from a voice messaging system to a telephone over a communications network, the telephone including a telephone speaker and a base and having a secure telephone device coupled between the speaker and the base, the voice messaging system having a cryptographic system, the voice messaging system coupled to the telephone by a clear communications path of the network, the method comprising the steps of:
- transmitting first signals from the cryptographic system of the voice messaging system to the secure telephone device, the first signals for use in converting the clear communications path to a secure communications path; and
- transmitting recorded voice message signals over the secure communications path by the voice messaging system.
