Authentication and key distribution methods in mobile computing environments
Zhang Bin, WU Jiang-xing · 2004
This paper discusses the authentication problem of the mobile user based on public key cryptosystem and shared key cryptosystem. We analyze several authentication and key distribution protocols in mobile environment. Weaknesses of each protocol are pointed out. A global initial authentication and key distribution method based on public key certificate chain is presented. It is argued that using hybrid system is feasible in order to authenticate the mobile user.
