A Key Distribution Scheme with Directly Mutual Authentication

Abstract

This paper presented a key distribution scheme based on the Yacobi scheme that does not use the secret key provided by key distribution center, but uses instead a random number generated by the user. The scheme is independent of the exposure of the secret key. This paper also presented the key distribution schemes based on the Diffie-Hellman (DH) and ID(identity). The scheme is based on the solving of the discrete logarithm and prime resolution into factors are better on the expose of secret key. The proposed scheme based on the DH has directly mutual authentication between users and is able to defend the network from impostors. The proposed key scheme based on the DH was applied to point-to-multipoint, and broadcasting networks via satellite.
