Session Initiation Protocol - Discovery Service (SIP-DS)
Click to view larger
Description:
The Naval Research Laboratory (NRL) has developed a system architecture for establishing network communications between users having disparate encryption devices via standard Session Initiation Protocol (SIP). The SIP concept of presence is exploited to accomplish encryption device discovery, Plain Text Database (PTD) database exchange, device peering, and the establishment of encryption device policy associations. This domain 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 peers and exchange PTD information. Additionally, SIP-DS allows one encryption device to proxy PTD information for other encryption devices unable to implement this method. This new method will not require a new IETF standard or any modification to existing IETF standards, nor are any specifically configured infrastructure or network devices required.Advantages/Features Include:
- Works with any SIP stack, router or encryptor on any network, allowing domain discovery between any type 1 encryption devices, firewall or secure VPN edge device
- Provides cost savings by allowing the automation of encryption device, firewall or secure VPN edge device setup
- Does not require IETF standards modification to adopt SIP-DS
- Capable of supporting multiple discovery functions including domain PTD, Policy, QoS and RIB
- Scalable, supporting both Peer-to-Peer and Client-Server for intranet and internet domain discovery
- Supports terrestrial and mobile networks and Ipv6, Black Core or Stripped networks.
Applications Include:
- Encrypted network administration
