摘要: 为保障大电网安全,解决电力物联网复杂通信网络中网关抗攻击能力弱、设备集中式接入认证方式导致认证中心负荷大、效率低、存在安全隐患等问题,提出了一种基于区块链的分布式动态网关架构以及接入认证机制。将区块链的共识机制运用到主网关的动态切换过程,形成了分布式的动态网关结构;结合门限秘密共享算法提出一种可信、灵活的分布式接入认证方式,并将接入认证过程中所涉及的设备ID等数字信息存入区块链数据存储结构中以提高认证过程的安全性。为了从理论和实践上说明该方法的有效性,进行了安全性分析与实验。结果表明,所提出的动态网关架构可以抵御物联网常见攻击,接入认证机制可以为电力物联网设备提供高度安全的接入认证保障。

Abstract: In order to ensure the cyber security of bulk power system, a distributed dynamic gateway architecture based on blockchain and access authentication mechanism is proposed regarding the vulnerabilities of gateway to cyberattacks in the complex communication network of power Internet of Things, as well as the problems of heavy loading, low efficiency and potential security risks caused by the equipment access authentication mode in the centralized platform. The consensus mechanism of blockchain is applied to the dynamic switching process of the main gateway to form a distributed dynamic gateway structure. The device ID and other digital information involved in the access authentication process are stored in the blockchain data storage structure to improve the data security in the authentication process. To demonstrate the effectiveness of the method in theory and practice, security analysis and experiments are carried out. The results show that the proposed dynamic gateway architecture can boost the resistance to the general attacks of the Internet of Things. The access authentication mechanism can also provide access authentication assurance with high security for power Internet of Things devices.
