This paper presents modified Yacobi (1989) scheme that does not use the secret key provided by the key distribution center, but uses instead a random number generated by the user. This paper also presents the modified Diffie-Hellman (1976) and ID (identity) method which has directly mutual authentication between users and is able to defend the network from impostors. The proposed scheme based on the DH was applied to VSAT satellite communications and simulated on a PC using Montgomery (1993) algorithm and MD5 (Message Digest) for a feasible study of secure VSAT satellite communications
