Industrial control identity authentication method and device with state cryptographic algorithms

Abstract

The invention discloses an industrial control identity authentication method and device with state cryptographic algorithms, and relates to the field of industrial control safety. The device is composed of an identity authentication authorization management server and a state cryptographic serial port identity authentication terminal, wherein the identity authentication authorization management server comprises a TCM security chip, an operating system, an identity authentication authorization management system, an industrial firewall, an outer network interface, an inner network interface and a BIOS, and the state cryptographic serial port identity authentication terminal comprises a CPU, a confidentiality memorizer and a chip operating system. The reliable operation of the identity authentication authorization management server, the authorization of different authority limits of a read-only access terminal, a configuration modification terminal and a safety management terminal and the authority limit achieving method of three kinds of state cryptographic serial port identity authentication terminals for accessing an industrial control system through an outer network are achieved through the combining application of the state cryptographic algorithms, SM1, SM2 and SM3. The method and device can effectively and strictly manage the boundary of the industrial control system and the outer network to meet the needs of the industrial control system safety of our country, and the method and device have the advantages of being safe and reliable, fast in promotion, easy and convenient to maintain, low in operating cost and universal in use.

Description

technical field [0001] The invention relates to the field of industrial control security, in particular to solve the border security problem of connecting an industrial control system integrated with high-speed industrial Ethernet ring network and automation platform software with external networks and other systems. Background technique [0002] The Ministry of Industry and Information Technology of the People's Republic of China issued the "Notice on Strengthening Information Security Management of Industrial Control Systems" in October 2011. The "Notice" pointed out that data acquisition and monitoring SCADA, distributed control system DCS, process control system PCS, and Industrial control systems such as programmable logic controller PLC and remote terminal RTU are widely used in the fields of industry, energy, transportation, water conservancy and municipal administration to control the operation of production equipment. Once there is a loophole in the information secu...

Problems solved by technology

Although TCG is a non-profit organization and the technology of TPM is also open, international giants such as Microsoft, Intel, and IBM still master the core technology, so security equipment using TPM standards will pose a huge threat to national information security
