Abstract

Separate IP data streams, including both voice (VoIP) and data sources, are routed over a single network data stream, encrypted by a single KIV encryption unit, and transmitted as a single packet data stream including both computer and voice data. Integration of the use of a VoIP data stream, together with data sources, and encrypted through a single serial encryption unit such as a KIV-7 enables the encryption of both voice and data using a single KIV encryption unit. After encryption by the Type 1 encryption unit (e.g., KIV-7) in a remotely deployed, secure communication system, the single encrypted data stream is encapsulated into IP packets. The IP packets are addressed to a distant IP device that removes the encapsulated, encrypted data and passes it to a similar Type 1 KIV device for decryption, and distributed to voice devices and computer devices via another voice-enabled router.

Claims

1. A method of encrypting and transmitting voice and data together in a secure communication system, said method comprising:

packetizing voice data into a voice-over-IP (VoIP) data stream;

encrypting said VoIP data stream through a Type 1 encryption unit into an encrypted data stream; and

encapsulating said encrypted data stream in IP packets for transmission.
