For example, in the application of access control, SM 1 algorithm is used for identity authentication and data encryption communication, so as to verify the legitimacy 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.
State secrets are an encryption and decryption algorithm;
State secret is an encryption and decryption algorithm, similar to RSA algorithm. The reason why the word "country" is added to state secrets shows that its standards come from our country, not from the United States like most algorithms on the market at present.
State secrets are not an algorithm, but many kinds. At present, there are many algorithms, such as SM 1, SM2, SM3, SM4 and so on. These algorithms have different implementations and functions.
