In order to solve the problem of poor security protection ability of terminal equipment in current industrial control system, combining digital signature technology based on public key infrastructure and secret sharing scheme, an authentication scheme for distributed industrial control system terminal is proposed in this paper. In the process of authentication, digital signature technology based on public key infrastructure is used to deliver secret shares. The existence of the trusted center T is no longer required. This solves the problem of key escrow, prevents illegal personnel from using the name of trusted center T to deliver fake secret shares to industrial control terminal equipment, and enhances the security and reliability of the whole control system. The analysis shows that the authentication scheme can realize the authentication function between the engineer station and PLC terminal equipment in the multi-machine cooperation scenario in the industrial control system, prevent the intrusion of external personnel, ensure that the network data will not leak, and ensure the data security to the greatest extent.
