摘要:Wireless sensor networks (WSNs) have been deployed for several applications that useM2M communications. Malicious code propagation is considered a serious threat on WSNs.In this paper, we considere a simple, distributed remote attestation method for a WSNthat does not require secret information, precise timing measurement, or a tamper-resistantdevice. Each node holds a value for the attestation of other nodes, and sensor nodes checkthe validity of each other's data. A sensor node terminates itself to prevent propagationof malicious code, when the sensor node nds a unexpected changes in stored program anddata. We analyzed the probability of success in protecting the WSN against malicious codeunder random network models. The analyses conrmed the feasibility of the attestationscheme and we obtained a fundamental approach to nding an appropriate frequency forattestation.
