Abstract: Recently, Park and Lim (1998) proposed two key distribution systems for secure VSAT
satellite communications. One provides indirect authentication, and another scheme enables that
two parties can directly authenticate each other. However, this article will show that the proposed
schemes are insecure enough by presenting two impersonation attacks on them. Besides, an improved
scheme will be proposed, which is secure against the impersonation attack and provides
direct mutual authentication between two parties.
