Abstract

A critical security threat in a WSN is the compromising of sensor nodes. Not only can attackers use such vulnerability to eavesdrop on the dataflow, but could also inject bogus information into the network. However, most current secure data collection methods trade fault-tolerant ability for end-to-end protection, thus with poor performance. This work proposes CRINet, a secure and fault-tolerant data collection scheme with group key management mechanism. To achieve high reliability, sensing data would be transferred to the sink through multi-path. EBS is applied in CRINet for group key management in order to reduce re-key efforts. Simulation results demonstrate that CRINet scheme is superior in terms of data confidentiality and availability.
