Encapsulation security protocol design for local area networks

Abstract

Construction of a simple local area network encapsulation security protocol is discussed. The paper illustrates the way that the key distribution scheme, the confidentiality algorithm, and the integrity algorithm drive the protocol construction. A Needham/Schroeder based key distribution scheme, DES Cipher Block Chaining, and the Message Authentication Code are used as building blocks for a sample protocol. The sample protocol provides data origin authentication, confidentiality, and integrity.
