Sensor nodes may be deployed in hostile environments. An adversary may compromise the sensor nodes and inject false data into the network, which wastes scarce energy resources of the forwarding nodes. Existing schemes can effectively resist false data injection, but most of them do not consider the IDentifiers (IDs) attack, the en-route nodes check only the Message Authentication Codes (MACs) and do not verify the nodes IDentifiers (IDs) of the endorsing reports. In this paper, the authors propose a key chain and different operation (KCEFP) based on one-way key chain.
