초록
Because a sensor node must operate on a tiny battery, the goal to eliminate energy inefficiencies leads the current researchers excavating for new techniques to advocate. As sensor networks edge closer towards wide spread deployment, security issues become a central concern. So far much research has focused on making sensor networks feasible and useful, and has not concentrated much on security issues especially computationally inexpensive techniques. In this paper we introduce a simple scheme relying on one-way hash-functions that greatly enhances location privacy by changing traceable identifiers on every read getting by with only a single, unreliable message exchange. Thereby the scheme is safe from many threats like eavesdropping, message interception, spoofing, and replay attacks.
