Recently, Das proposed a secure two-factor user authentication scheme based on hash function, which is efficient enough to be implemented on most of the target resource-constrained devices, such as low-computation smart cards and low-power sensor nodes in wireless sensor networks (WSNs). As Das claimed, the proposed scheme can resist attacks and threats such as many logged-in users with the same login identity, stolen-verifier, guessing, impersonation and replay. Unfortunately, we find that Das… CONTINUE READING
