A Model of Key Agreement Protocol using Polynomials over Non-Cummutative Division Semirings

[摘要] The basic aim of key exchange is that two people who can only communicate via an insecure channel want to find a common secret key without any attack. In this paper we show a model of key-agreement protocol using polynomials over non-commutative division semiring for network security. It is proved that the proposed protocol meets several security attributes under the assumption that the polynomials over the non- commutative division semiring.
