Standards for computer systems security: An interoperability analysis of SDNS SP3 and ISO NLSP

In the open systems interconnection (OSI) communications framework, standards are being proposed for cryptography-based security protocols that will provide security services to the user. Many of these security protocols provide almost identical security services and are being pursued in groups that include ANSI, IEEE, IETF, and NATO. Two of the current security protocols defined for the network layer of the OSI communications stack that are being proposed for use by the US Department of Defense and commercial networks are examined, and the issue of interoperability between these two protocols is addressed
