Wireless sensor networks (WSNs) have many applications and are deployed in a wide variety of areas. They are often deployed in potentially adverse or even hostile environment so that there are concerns on security issues in these WSNs. Recently, an anonymous user authentication and key agreement scheme (AUAKAS) was proposed based on symmetric cryptosystem in WSNs. It is claimed in AUAKAS that it assures security against different types of attacks including impersonation attacks. However, this paper shows that AUAKAS does not cope from user impersonation attack and gateway impersonation attack from the legally registered user on the gateway. The security analysis could guide the required features of the security scheme to be satisfied.
