Entity Recognition for Sensor Network Motes
Message authenticity (knowing â€śwho sent this messageâ€ť) is an important security issue for sensor networks, and often difficult to solve. Sometimes, it may be sufficient and more efficient to solve the simpler entitiy recognition problem, instead: â€śis the message from the same entity that sent the previous messages?â€ť. This paper describes entity recognition for sensor network motes. A protocol presented at SAC 2003  is shown to be insecure, and a new and provably secure protocol is proposed.
