Wireless sensor networks (WSNs) have its applications in many domains such as agriculture, medicine, safety, and industry. Due to its wireless channel, it is vulnerable to many security threats. To provide end‐to‐end secure communication, various authentication and key agreement protocols have been discussed. Recently, Li et al have designed a mutual authentication and key agreement protocol for WSNs. However, it is found that this scheme does not resist to offline password guessing, device stolen, insider, and replay attacks besides user traceability problem. In this paper, a mutual authentication and key agreement protocol by overcoming the deficiencies of their scheme is proposed. Its formal security verification is shown using ProVerif tool. Its performance analysis is presented in terms of communication cost, computational cost, storage cost, and security features along with the other related schemes. It offers more security features than the other related schemes.
