Entity Recognition for Sensor Network Motes

S. Lucks , E. Zenner , A. Weimerskirch and D. Westhoff

Sometimes, it may be sufficient and more efficient to solve the simpler entitiy recognition problem, instead: “is the message from the same entity that sent the previous messages?”. This paper describes entity recognition for sensor network motes. A protocol presented at SAC 2003 [5] is shown to be insecure, and a new and provably secure protocol is proposed.
