一种适用于SM2公钥密码算法的可变密钥生成方法及装置
By using the variable key generation method of the SM2 public-key cryptography algorithm, public and private key pairs are dynamically generated, solving the problems of private key security and resource waste. This allows for periodic updates of the private key without the need for frequent certificate signing, thus saving resources.

AI Technical Summary
In existing technologies, the security of private keys is difficult to guarantee, resulting in short lifecycles for digital certificates and high frequency of certificate signing by CA authorities, which wastes computing, storage, and network communication resources.
Using the SM2 public-key cryptography algorithm, and through the new certificate signing strategy of digital certificate authorities, multiple random numbers are generated and the value of n is calculated to dynamically generate public and private key pairs. The private key is changed periodically, reducing the number of signings required by the CA.
It effectively saves computing, storage, and network communication resources, enables periodic updates of private keys without the need for frequent certificate signing, and improves private key security.
