Trusted measurement and control network authentication method based on double secret values and chaotic encryption

Abstract

The invention relates to a trusted measurement and control network authentication method based on double secret values and chaotic encryption. The method specifically comprises the steps: on the basisthat a trust chain is constructed through trusted computing to achieve a safe and trusted operation environment, identity authentication and key negotiation processes are achieved through double secret values and a chaotic public key password, safe transmission and verification of a user identity certificate are achieved, and therefore, a safe and trusted data transmission channel is constructed.The identity authentication method provided by the invention comprises multiple links of user identity security generation, reading protection packaging, security transmission, key negotiation and the like, and a password function with uniqueness and confidentiality is adopted in each link to perform data security generation, so that the security of access of authentication equipment in an industrial measurement and control network is ensured.

Description

technical field [0001] The invention relates to a technical method for identity authentication by adopting a double secret value and a chaotic encryption key agreement algorithm in an industrial measurement and control network, belonging to the field of industrial control network security. Background technique [0002] With the gradual acceleration of my country's industrial informatization, more and more communication technologies and embedded applications have been applied to industrial production networks. While enjoying the convenience brought by high-tech to the production process, it also reflects information security issues to varying degrees. Once some uncontrolled devices are connected to the industrial measurement and control network, through denial of service attacks or penetration mining of communication protocols, the loopholes in the protocol can be used to attack the core device of the production system and modify the application configuration of the device O...
