Abstract

Sensitive, Standard Telephone Equipment (STE) data is encapsulated into IP packets in a remotely deployed, secure communication system. The IP packets are addressed to a matching IP encapsulator/decapsulator device over the public Internet or other IP protocol network, that then passes it to a similar STE device over an ISDN link for decryption. The present invention is embodied in a system that provides secure Voice-Over-IP (VOIP), video and data network functionality in a single, small size deployable case, to a remote user. Most importantly, the embodiment allows for the routing of bulk encrypted (i.e., secure) data over a public network, e.g., the Internet.

Claims

1. A method of cloaking encrypted data from a Standard Telephone Equipment (STE) secure telephone, comprising:

encapsulating an ISDN serial data stream of encrypted data received from a Standard Telephone Equipment (STE) secure telephone, into IP packets; and

transmitting said IP packets of encrypted data on a public IP network.
