Wireless sensor network (WSN) have been applied in many different areas. Mutual authentication is an important service in WSN. In 2010, Chen and Shih proposed a robust mutual authentication (RMA) protocol for WSN. However, this paper points out that Chen-Shih's RMA protocol has some drawbacks: (1) user impersonation attacks by a malicious registered user, (2) GW-node impersonation attacks by a malicious registered user, (3) sensor node impersonation attacks by a malicious registered user, (4) privileged insider attacks, and (5) time synchronization problem.
