中文摘要:

随着电力物联网的建设，终端接入数量的大量增加，实现低延迟和提供实时服务是传统电力物联网面临的两大挑战。虽然在电力物联网系统中已经有一些加密方案被设计来促进安全通信，但是现有的方案通常不支持匿名和灵活的密钥管理。文中基于区块链的共识机制，在电力物联网系统中保证了分散节点在区块链系统中实现一致性。提出了一种基于区块链的智能电网系统互认证和密钥方案，基于区块链共识机制的特性，所提方案可以支持高效的条件匿名和密钥管理，对终端（TA）与数据聚合器（DA）之间安全私有通信和密钥管理问题提出解决方案，提供了一个有效的密钥更新和撤销算法。对所提出方案的存储成本及时间成本进行了实验数据分析，实验结果与其他文献分别提出的三个密钥管理认证方案进行了对比，结果表明所提方案在存储成本及时间成本有明显优势。最后，进行了安全和效率之间的讨论分析，对未来电力物联网建设方面提出了建设性意见。

英文摘要:

With the construction of the 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. In this paper, based on the consensus mechanism of the block chain, ensures that the decentralized nodes in the power Internet of Things system are guaranteed to achieve the consistency in the block chain system. A block chain-based mutual authentication and key scheme for smart grid systems is proposed. Based on the characteristics of the block chain consensus mechanism, the scheme can support efficient conditional anonymity and key management. It proposes a solution to the problem of secure private communication and key management which is effective for terminal (TA) and data aggregators (DA), 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 other papers respectively. The results show that this scheme has obvious advantages in storage cost and time cost. Finally, a discussion and analysis between safety and efficiency are carried out, and constructive opinions are put forward for the construction of the future power Internet of Things.
