An Enhanced and Secure Biometric Based User Authentication Scheme in Wireless Sensor Networks Using Smart Cards

Over the last twodecades, several researchers have recommended many remote user authentication schemes, following since introducing the concept way back in 1981. Researchers are continuously trying to enhance the security in authentication protocols by incorporating the several features into their work. A few years back, Turkanovic et al. (Ad Hoc Netw 20:96-112, 2014) have presented a novel work for authenticating users in IOT environment using smart cards for wireless sensor networks. In this paper, we have demonstrated that their scheme doesn't resist many possible security threats and have numerous flaws, and also proposed an enhanced and secure biometric-based user authentication technique to overcome their weaknesses. The stated protocol not only overcome from the flaws of Turkanovic et al.'s scheme but also reduce the computation overhead as well. Later, to proving the mutual authentication among the entities and session key secrecy of the proposed scheme has also been verified by ProVerif (2.0) simulation tool.
