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.
Claims15
A method of cloaking telephone communications, comprising:
- formulating a single digitally encrypted secure serial data stream from at least one of a telephony signal and a data signal;
- encapsulating said single digitally encrypted secure serial data stream comprising said at least one of a telephony signal and a data signal into IP packets;
- establishing a first data tunnel between a local black side router and a remote gateway router;
- establishing a second data tunnel between a local IP encapsulator and a remote IP encapsulator;
- and
- transmitting said IP packets of said single digitally encrypted secure serial data stream on a public non-secure IP network over said first data tunnel and said second data tunnel.
Apparatus for cloaking telephone communications, comprising:
- means for formulating a single digitally encrypted secure serial data stream from at least one of a telephony signal and a data signal;
- means for encapsulating said single digitally encrypted secure serial data stream comprising said at least one of a telephony signal and a data signal into IP packets;
- means for establishing a first data tunnel between a local black side router and a remote gateway router;
- means for establishing a second data tunnel between a local IP encapsulator and a remote IP encapsulator;
- and
- means for transmitting said IP packets of said single digitally encrypted secure serial data stream on a public non-secure IP network over said first data tunnel and said second data tunnel.
