Research on Secure Aggregation Scheme based on Stateful Public Key Cryptology in Wireless Sensor Networks

Wireless sensor network (WSN) is an important part of the Internet of Things (IoT) and technical support for ubiquitous communication. Data aggregation technology reduces the network traffic overhead and extends the effective working time of the network, but the continued operation of the wireless sensor networks will increase the probability of the aggregation node being captured and probability of the aggregated data being tampered. Thus it will seriously affect the security performance of the network. For network security issues, this paper proposed a secure aggregation scheme based on Stateful Public Key Cryptography (SPKC) for WSNs, which employs a new stateful public key encryption to provide an efficient end-to-end security. Moreover, the security aggregation model will not impose any bound on the aggregation function property, so as to realize the low cost and high security level as the same time
