Authentication method and device for industrial control system

Abstract

The invention discloses an authentication method and device for an industrial control system, and belongs to the technical field of information security. The method comprises the steps that an accountnumber sent by a terminal and an authentication dynamic password corresponding to the account number are received, the account number corresponds to industrial control equipment within the jurisdiction range of a safety management platform, and the industrial control equipment belongs to different service levels; an authority level of the account is acquired, wherein the authority level of each account corresponds to a service level to which the industrial control equipment belongs; and the authentication dynamic password corresponding to the account is authenticated based on the authority level of the account to obtain an authentication result. The authentication method is suitable for the industrial control system, and can perform identity authentication based on multi-level authority levels on a user accessing the industrial control system, thereby effectively preventing an illegal user from accessing the industrial control system, and protecting core equipment of the industrial control system.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an authentication method and device for an industrial control system. Background technique [0002] Industrial control system (referred to as industrial control system) is a system composed of various automation control components and process control components to ensure the automatic operation of industrial infrastructure. As an important part of national industrial infrastructure, industrial control system's security has become an important strategic issue involving national security and stability. Identity authentication is one of the effective means to reduce the security risk of industrial control system. Currently commonly used identity authentication methods include user name and password authentication, biometric authentication, and dynamic password authentication. However, these identity authentication methods are all designed for IT systems. Since the con...
