This paper proposes a new efficient and secure multiserver authentication scheme based on one-way hash function without verification table to minimize the complexity of hash operation among all users and fit multi-server communication environments. Compare with related multi-serve authentication schemes, the proposed scheme has strong security and enhanced computational efficiency. Thus, the proposed...
Generally, a remote autonomous object acts with its own thread of control. In 2003, Novikov and Kiselev proposed an authentication scheme of the user from the remote autonomous object with public key cryptosystem which is applicable in the telecommunications system. In 2005, Yang et al.,however, has pointed out that the Novikov-Kiselev scheme is insecure against the man-in-the-middle attack. This...
In 2008, Tsai proposed an efficient nonce-based authentication scheme for Session Initiation Protocol (SIP). The current paper, however,demonstrates that Tsai's authentication scheme is still vulnerable to off-line password guessing attacks, Denning-Sacco attack and stolen-verifier attacks, and does not provide perfect forward secrecy. We also propose a new secure and efficient authentication scheme...
