Abstract

The invention discloses an efficient equipment instruction authentication system and method based on a certificateless signature, and the system specifically comprises a trusted system Administrator (TSA), an engineer station (ES), and an engineer (ER). The method comprises the following steps: system initialization, generation of a partial signature private key, selection of a secret value, generation of a signature public key, signature of an equipment instruction and signature verification. According to the method, the device instruction edited by an engineer ER is ensured not to be modified or maliciously counterfeited before being executed, the instruction authentication efficiency of the ICS is improved, and the requirement of the ICS for actual application can be better met.

Description

technical field [0001] The invention belongs to the technical field of industrial control system (Industrial Control System, ICS) equipment instruction authentication technology and the technical field of industrial control equipment instruction integrity and tamper-resistant modification, and relates to a method for equipment instruction authentication in an industrial control system, especially for industrial control systems. The characteristics of the system field, the requirements for the integrity of equipment instructions, and the efficiency requirements for the engineer station to verify the signatures of equipment instructions uploaded by different engineers, an efficient equipment instruction authentication system and method based on certificateless signatures through certificateless signature technology. Background technique [0002] ICS is an automatic control system composed of computer and industrial process control components. It has been widely used in electric...
