Abstract: The invention discloses an invalid certificate data smooth-transition protection method. In a transitional period, for old data, signature authentication on the old data is carried out by adoption ofa first signature certificate; furthermore, the old data is decrypted by adoption of a first encryption certificate; then, encryption protection on the decrypted old data is carried out by adoption ofa second encryption certificate till updating of all the old data is completed or the data is filed; for new data, signature authentication on the new data is carried out by adoption of a second signature certificate; and furthermore, encryption protection on the new data is carried out by adoption of the second encryption certificate. By means of the invalid certificate data smooth-transition protection method disclosed by the invention, the problem that the old data cannot be used due to certificate expiration, algorithm change and certificate revocation because of some security requirements of certificates in the use process of digital certificates can be perfectly solved through the scheme; and finally, the data security and convenience are ensured.
