Özet

Dealing with captured nodes is generally accepted as the most difficult challenge to wireless sensor network security. By utilizing the low-cost property of sensor nodes, we introduce the novel concept of one-time sensors to mitigate node-capture attacks. The basic idea is to load each sensor with only one cryptographic token so that the captured node can inject only a single malicious message into the network. In addition, sybil attacks are avoided and explicit revocation is not necessary using one-time sensors. By using public key techniques, one-way hash functions and Merkle's hash tree, we also show efficient implementations and interesting tradeoffs for one-time sensors. © Springer-Verlag Berlin Heidelberg 2005.
