Abstract

This paper researched on Needham-Schroeder symmetric key authentication protocol based on BAN logic. It pointed out the flaw of the protocol which can be used by replay attack and improved the protocol by adding nonce in the transferred message. Then it listed the improved NS authentication protocol. Finally, this paper proved the improved protocol successful and available with BAN logic.
