摘要

本文提出了一种改进的Yacobi方案，该方案不使用密钥分发中心提供的密钥，而是使用用户生成的随机数。本文还提出了一种改进的带有ID (identity)的Diffie-Hellnan (DH)方案，该方案在用户之间直接相互认证，并能够防御网络中的冒名顶替者。将该方案应用于VSAT卫星通信中，并利用Montgomery算法和MD5 (Message Digest)算法在PC上进行了仿真，对VSAT卫星通信的安全性进行了可行性研究。将所提出的方案应用于卫星数据传输延迟时间约200 ~ 600ms的VSAT卫星通信中，结果合理。

Key distribution for secure VSAT satellite communications

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.
