Session Initiation Protocol Network Encryption Device Plain Text Domain Discovery Service
Abstract:
This report provides a method for cryptographic isolated domains to discover other cryptographic isolated domains by using the IETF Session Initiation Protocol SIP. This method, called the SIP Network Encryption Device Plain Text Domain Discovery Service SIP-DS, will not require a new IETF standard or any modification to existing IETF standards, nor are any specifically configured infrastructure or network devices required. This discovery method allows any encryption device, be it typical U.S. government Type I encryption devices such as TACLANE, HAIPE, or FASTLANE, or any non-government cryptographic devices implementing this technology, to find and exchange plain text domain PTD information. Additionally, SIP-DS will allow one encryption device to proxy PTD information for other encryption devices unable to implement this method.
