Research on Authentication and Key Negotiation Based on Smart Water Environment

Abstract

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.
