The invention provides a method and system for verifying a user authorization certificate through verifying authorization time. The method comprises that: obtaining a hardware identifier, a firmware identifier and electric timekeeping time on a hard disk of a client itself by the client, encrypting and transmitting to a server; manufacturing a verification certificate by the server, generating effective authorization time according to the electric timekeeping time on the hard disk, writing the hardware identifier, the firmware identifier and the effective authorization time in the verification certificate, carrying out digital signing, encrypting the verification certificate by the hardware identifier and the firmware identifier, thus obtaining the verification certificate; and judging whether the verification certificate is effective according to the effective authorization time. Encryption and decryption are carried out to the verification certificate by using the hardware identifier and the firmware identifier; the defects that the certificate is forged and the information in the certificate is tampered are overcome; the defect that the system time is modified so that whether the certificate is illegal and effective cannot be judged is overcome by using the electric timekeeping time.
Description
Technical field [0001] The present invention involves the field of communication security, especially the method and system that involves a method and system that verifies the user authorization certificate by verifying authorization. Background technique [0002] The traditional method of verifying the user authorized certificate is to use the public key to encrypt the information, and then send the information to the server. After the server signs a certificate with a private key, send it to the user.The system time judgment whether the certificate is valid. [0003] In addition, after using the public key decryption certificate to obtain information, the user can reintermine the certificate and replace the original certificate and public key by using its own public key.Whether the public key is faked and the public key is replaced, the validity time of the certificate may also be modified, so it is impossible to determine whether the certificate is legal and effective.
