Robust dynamic user authentication scheme for wireless sensor networks

Abstract

In recent years, wireless sensor networks (WSNs) have been widely used in different domains. For instance, WSNs can be deployed in insecure and unattended environments. In this regard, user authentication is a critical issue for WSNs. In this paper, we propose a user authentication protocol in WSNs, which is variation of strong-password based solution proposed by Wong et al. The proposed protocol is evaluated and compared with the previous schemes.
