Cryptanalysis of a Multifactor Authentication Protocol

Cybercrime analysis reports state that the crime percentage has been doubled from past 3 to 4 years, and most of the crimes are being successful due to the lack of proper identity verification mechanism that is nothing but the authenticity verificationmechanism. The authentication of the user can be done by various authentication protocols but still, the attacks are being success; this shows the necessity of improving the efficiency of the authentication algorithms, and this can be done accurately by analysis various existingmechanisms proposed by various researchers. On analyzing the various protocols of authentication, the loop pits of the existing schemes can be recorded, which gives an ideology of filling the loopholes of the same. Therefore, this paper analyzes the most recently proposed multifactor authentication scheme by Mishra et al. Based on various characteristics that are to be considered in designing an authentication protocol, the scheme is been analyzed. A detailed explanation of various vulnerabilities of Mishra et al.'s scheme is given in this paper.
