Prototyping SP4: A Secure Data Network System Transport Protocol InteroperabilityDemonstration Project

摘要

The Secure Data Network System (SDNS) project implements computer to computercommunications security for distributed applications. The internationally accepted Open Systems Interconnection (OSI) computer networking architecture provides the framework for SDNS. SDNS utilizes the layering principles of OSI to implement secure data transfers between computer nodes of local area and wide area networks. SDNS implements SP4, a security protocol at the OSI Transport layer that provides end-to-end reliable transparent data communications with confidentiality and integrity security services. Laboratory prototypes of SP4 formed the basis of proposed voluntary national standards and will form the basis for future security enhancements to existing Government OSI Profiles.
