Cryptoanalysis of Lightweight and anonymous three-factor authentication and access control protocol for real-time applications in wireless sensor networks

Abstract

Wireless sensor networks are used to monitor various environmental conditions such as temperature, sound, pollution level, humidity, wind and so on. Therefore, fast and secure authentication is important and requires a lightweight protocol that is secure. AmirHosein et al. proposed a 3-factor protocol in wireless sensor networks, but we found that the protocol in the wireless sensor network had some weaknesses. Firstly, it is a weakness in smart card deodorization. And it is also vulnerable to user impersonation. Moreover, it is possible to attack the session key. In this paper, we describe this weakness and prove AmirHosein et al.’s scheme is insecure. © 2020, Springer Nature Singapore Pte Ltd.
