SOFTWARE KEY UPDATING METHOD AND DEVICE

摘要

Provided in an embodiment of the present invention are a software key updating method and device. A trusted client device receives key information and verification information corresponding to the software and transmitted by a server, the key information containing a to-be-updated first software public key signature and a new second software public key signature, and the verification information containing software verification information; if a valid first software public key signature corresponding to the software and stored in the trusted client device is consistent with the received first software public key signature, then checking whether the software verification information is valid; and if the software verification information is valid, then updating the valid first software public key signature corresponding to the software and stored in the trusted client device as a second software public key signature. With the above solution, the present invention can remotely update a software key signature on a trusted client device, thus preventing the problem of being unable to update an invalid key.
