For example, the data to be transmitted is of low importance, even if it is intercepted, it will not cause harm to the user, and the data encryption type that matches the security level is determined to be a low level. The data to be transmitted is of high importance, such as identity information, password information, account information, etc., and the data encryption type that matches the security level is determined to be a higher level.

For example, different data encryption types correspond to different encryption hardware entities, and for data encryption types with high importance corresponding to a relatively large number of encryption hardware entities, the encryption level is increased. Data encryption types of lesser importance correspond to a relatively smaller number of cryptographic hardware entities. For another example, the encryption methods adopted by the same encryption hardware entity can be different. For data encryption types with higher importance and data encryption types with lower importance, determine the data encryption type with higher importance when the same encryption hardware performs data encryption. Use higher levels of encryption, and less important data encryption types use lower levels of encryption.
