Commercial passwords refer to technologies, products and services that encrypt and protect information that does not involve state secrets. Its core is to provide security protection for commercial data and information systems, which is universal, basic and systematic. State secret is a domestic cryptographic algorithm approved by the State Cryptography Bureau.
State secret algorithm is a series of cryptographic algorithm standards formulated by China government to ensure national information security. These algorithms include SM 1, SM2, SM3, SM4, etc. They have been widely used at home and abroad. Among them, SM 1 is a symmetric encryption algorithm, which is mainly used for data encryption. SM2 is an asymmetric encryption algorithm, which is mainly used for digital signature and identity authentication. SM3 is a hash function algorithm, which is mainly used for data integrity checking. SM4 is a symmetric encryption algorithm, which is mainly used for data encryption.
Use cases of state secrets
In the application of access control, SM 1 algorithm is used for identity authentication and data encryption communication to verify the validity of the card and ensure the authenticity of identity identification. Security is a key issue related to the interests of the country, city information, industry users and people. The State Cryptography Administration also gave guidance on the construction and upgrading of existing important access control systems, and strengthened the standardization of chips, cards and systems.
The cases of upgrading the national secret access control system are gradually increasing, and CPU cards, CPU card reading and writing devices, and key management systems based on independent domestic intellectual property rights are widely concerned. Some manufacturers launched a series of CPU card security access control products in 2009. At the 20 10 Beijing Expo, they showed a series of mainstream products and systems, such as CPU card access control system, a series of security access control card readers, and one-card system based on CPU card technology.
These manufacturers are pioneers in promoting national secret access control products, which makes this series of CPU card access control systems widely used in high-security fields such as government, prisons, justice, military enterprises and large public intelligent buildings.
