my country's SM2 algorithm is an asymmetric cipher, and the cipher is asymmetric. The relevant knowledge is introduced as follows:

1. Domestic cipher algorithm:

1. National cipher That is, the domestic encryption algorithm recognized by the State Cryptozoology Bureau, that is, the commercial encryption. Commercial cryptography refers to technology that can implement functions such as encryption, decryption, and authentication of commercial cryptographic algorithms. Including cryptographic algorithm programming technology and cryptographic algorithm chip, encryption card, etc. implementation technology.

2. Commercial cryptography technology is the core of commercial cryptography. The state has classified commercial cryptography technology as a state secret. All units and individuals have the responsibility and obligation to protect the secrets of commercial cryptography technology. Commercial passwords have a wide range of applications and are mainly used to encrypt and protect sensitive internal information, administrative affairs information, economic information, etc.

3. For example, commercial passwords can be used for enterprise access control, transmission encryption and storage encryption of various sensitive information within the enterprise to prevent illegal third parties from obtaining information content. They can also be used for various security authentications and online banking. , digital signature, etc.

2. National Cryptozoology SM2 Algorithm:

1. The SM2 algorithm was released by the State Cryptozoology Administration on December 17, 2010. It is called the elliptic curve algorithm and is an asymmetric algorithm. Key algorithm, its encryption strength is 256 bits, and its security has obvious advantages compared with the currently used RSA1024.

2. In order to further expand the influence of my country’s cryptographic technology products, enhance the international competitiveness of my country’s cryptographic technology, and enhance its international voice, in the National Information Security Standardization Technical Committee and the Cryptocurrency Industry Standards Technical Committee and other relevant units, With vigorous promotion, my country has also made important progress in the internationalization of cryptographic algorithm standards.
