Multi-node Trusted Remote Attestation and Recovery Scheme for Power Industrial Control Terminal

With the development of energy Internet, the scale of power network is expanding day by day. Therefore, a large number of electric devices are exposed to the network, and its security has become the focus of attention. In addition, electric devices frequently enter and exit the network and update software configuration items. Based on the above problems, this paper proposes a multi-node trusted remote attestation and repair scheme for power industrial control terminal. Firstly, based on the non-interactive attestation protocol, it can not only prevent DDoS attacks, but also be suitable for highly dynamic swarm networks. Secondly, the hash algorithm based on the complete binary tree can not only accurately recovery the compromised device, but also reduce the burden of hash calculation for new software configuration items of the device. Finally, the security analysis and performance evaluation show that this scheme is a secure and efficient swarm attestation and recovery scheme.
