摘要： A first authenticator payload is obtained that includes a first authenticator random value. A first authenticator encrypted file is generated with an authenticator public key that is related to a client authenticator application. The first authenticator encrypted file is generated based on a first cryptographic algorithm. The first authenticator encrypted file includes the first authenticator payload. A first target payload is obtained that includes a first target random value. A first target encrypted file is generated with the first authenticator random value. The first target encrypted file is generated based on a second cryptographic algorithm. The first target encrypted file includes the first target payload.
