The cluster heads in hierarchical wireless sensor networks gather real time data from the other ordinary sensor nodes and send those data to a nearest base station. But, the main important issue is that how a user will get the real time data directly from a cluster head securely. To solve this problem, many user authentication schemes have been proposed in literature. In 2012, Das et al. proposed a dynamic password-based user authentication scheme for hierarchical wireless sensor networks and showed that their scheme is secure against all possible attacks. In this paper, we have pointed out that Das et al.’s scheme is insecure against insider attack, theft attack and session key recovery attack, and their scheme also suffers from dynamic cluster head addition overhead problem, limited number of cluster heads access problem and clock synchronization problem. To overcome these drawbacks, we have proposed an efficient and robust user authentication scheme for hierarchical wireless sensor networks without tamper-proof smart card in this paper. We have also shown that our scheme provides better tread-off among security and communication overhead compare to the Das et al.’s scheme.
