越来越多的国家正在探索智慧城市相关的智能设施，以造福社会。物联网智能设备的远程访问和控制虽然方便，但也存在一定的风险。智能设备可能会受到犯罪分子的攻击，这些犯罪分子会对生产环境造成严重危害。设计一种安全高效的保密通信方案显得尤为重要。现有的解决方案大多基于单服务器架构，存在安全性和效率方面的问题。针对智慧水利中认证和密钥协商易受SPOF和DDOS攻击的问题，提出了一种基于区块链的认证密钥协商技术。在密钥协商中，智能设备的身份不可篡改，可以有效抵御中间人攻击。在协议执行过程中，智能设备的节点是轻节点。密钥协商过程在智能合约中进行，降低了计算复杂度，提高了运行效率。本文还分析了该方案的安全性。
More and more countries are exploring smart city related smart facilities to benefit the society. Remote access and control of IOT smart devices is convenient, but there are also some risks. Smart devices may be attacked by criminals who will do serious harm to the production environment. It is particularly important to design a safe and efficient secure communication scheme. Most existing solutions to this problem are usually based on single server architecture, which has some problems in security and efficiency. Aiming at the problem that authentication and key agreement in smart water conservancy are vulnerable to SPOF and DDOS attacks, this paper proposes an authentication key agreement technology based on blockchain. In key agreement, the identity of smart devices can not be tampered with, which can effectively resist man in the middle attack. In the process of protocol execution, the nodes of smart devices are light nodes. The process of key agreement is carried out in the smart contract, which reduces the computational complexity and improves the operation efficiency. This paper also analyzes the security of the scheme.
