Abstract:

Cryptanalysis of Li et al.'s authentication protocol shows that it is vulnerable to masquerade attack, session key disclosure attack and forge smart card attack. To overcome these security flaws, an improved protocol is presented. This protocol proves secure against some possible attacks. Besides, the improved scheme maintains the features of identity anonymity, concise registration, simple operation, and so on.
