Increasing popularity of the multi-server architecture has propelled the research on the multi-server authentication schemes. Current dominating authentication schemes are smartcard based, verification table free schemes with passwords. Although these schemes have developed to be robust against most of the popular malicious attacks, they still have security weaknesses and their efficiency is generally low. In this paper, we analyze and formulate security issues in previously proposed schemes. And based on the formulation, an enhanced efficient and secure scheme is proposed. In the proposal, a novel “redundant key protection” is proposed to utilize. The proposed scheme is validated and verified by Colored Petri Nets.
