Cryptanalysis of Yang-Wang-Chang’s password authentication scheme with smart cards

Cryptanalysis of Yang-Wang-Chang’s password authentication scheme with smart cards

In 2005, Yang, Wang, and Chang proposed an improved timestamp-based password authentication scheme in an attempt to overcome the flaws of Yang-Shieh’s legendary timestamp-based remote authentication scheme using smart cards. After analyzing the improved scheme proposed by Yang-Wang-Chang, we have fo...
