Abstract :
This paper presents a modified Yacobi 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 a modified Diffie-Hellnan (DH) scheme with ID (identity) 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 the Montgomery algorithm and MD5 (Message Digest) algorithm for a feasible study of secure VSAT satellite communications. The results are reasonable when applying the proposed scheme to VSAT satellite communications which requires about 200-600 ms for delay time of data transmission using satellite
