The emerging growth of Internet-of-Things(IoT) technology, enable the adoption of many industrial applications. As an infrastructure point of view, Wireless Sensor Networks(WSN) attains utmost importance in industrial IoT. The security threats always remain serious issues for WSN. Recently, Li et al scheme presented a three-factor authentication scheme for IoT environments. This article reviews Li et al. protocol find out that their protocol is vulnerable to stolen-verifier-attacks, Anonymity and Traceability issues. We present, an improved authentication scheme to conquered the flaws in Li et al scheme. Furthermore, the proposed solution is formally verified with ProVerif. Moreover security inspection proves the robustness of the proposed protocol.
