Abstract

Summary: Wireless sensor networks (WSNs) underpin many applications of the Internet of Things (IoT), ranging from smart cities to unmanned surveillance and others. Efficient user authentication in WSNs, particularly in settings with diverse IoT device configurations and specifications (eg, resource‐constrained IoT devices) and difficult physical conditions (eg, physical disaster area and adversarial environment such as battlefields), remains challenging, both in research and in practice. Here, we put forth a user anonymous authentication scheme, relying on both biometrics and elliptic curve cryptography, to establish desired security features like forward and backward secrecy. We then make use of the Random‐or‐Real (RoR) model to prove the security of our scheme. We have implemented the proposed scheme in an environment compatible with WSNs. We show after conducting the comparison of the proposed scheme with some recent and related existent schemes that it satisfies various essential and desirable security attributes of a WSN environment. We conclude that the proposed scheme is suitable for the WSN scenario demanding high security. Abstract : In overall efficiency, our scheme has more computational complexity and communication overhead than its counterparts. But our scheme is a far better achiever with regard to functionality and security as compared to its counterparts. Our scheme maintains a balance between efficiency and security, which is imperative need in a WSN environment, and hence it is quite suitable for a secure and sensitive application in WSNs.
