基于共识机制的电力物联网群组密钥管理研究
Research on Group Key Management of Power Internet of Things Based on Consensus Mechanism
With the construction of the ubiquitous power Internet of Things, the number of terminal accesses has increased greatly, and achieving low latency and providing real-time services are two major challenges faced by the traditional power Internet of Things. Although there are already some encryption schemes designed to promote secure communication in the power Internet of Things system, the existing schemes generally do not support anonymous and flexible key management. Based on the consensus mechanism of the blockchain, this paper ensures that the decentralized nodes achieve consistency in the blockchain system in the power Internet of Things system. A blockchain-based mutual authentication and key scheme for smart grid systems is proposed. Based on the characteristics of the blockchain consensus mechanism, the scheme can support efficient conditional anonymity and key management. It is effective for terminal (TA) and data aggregators. (DA) proposes a solution to the problem of secure private communication and key management, and provides an effective key update and revocation algorithm. This paper analyzes the experimental data of the storage cost and time cost of the proposed scheme. The experimental results are compared with the three key management authentication schemes proposed by Amor, Mahmood and Jia respectively. The results show that this scheme has advantages in storage cost and time cost. obvious advantage. Finally, a discussion and analysis between safety and efficiency was carried out, and constructive opinions were put forward for the construction of the future power Internet of Things.
