Rodrigues,2009.” Robust Dynamic User Authentication Scheme for Wireless Sensor Networks”proceeding of the 5th ACM symposium on QOS and security for wireless and mobile networks

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. Categories and Subject Descriptor
