The SILs model describes the architectural framework that 802.10 is using to provide security in IEEE 802 LANs and MANs and delineates the scope of each of the other two standards and relationships between them. The two protocol standards described in the Model are Secure Data Exchange (SDE) and Key Management (KMP). The model also describes how SDE and KMP work in end stations and bridges, as well as how they are used to protect management traffic. The Model addresses issues that apply to all of SILs. It enables implementers and users of SILS to understand how the SILS protocols operate together and how each protoc9ol individually operates in an OSI environment, as well as an IEEE 802 environment. The Model also describes implementations of SILS protocols in end stations, as well as transparent implementations in IEEE 802 bridges. Amendment Standard - Inactive-Withdrawn. Withdrawn Standard. Withdrawn Date: Jan 16, 2004. An architectural description of the functions and location of SILS components is provided. The SILS components and their relationships to applications, communications protocols, system management, and security management are described.
