Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined arbitrarily with each other.

[0030] At present, the existing TrE technology has relatively mature and reliable solutions for managing and storing sensitive information. Due to the existence of the trust chain in the trusted environment, unauthorized access and modification of the software in the trusted client device is not allowed, and the legality ve...

Abstract

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.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a software key updating method and device. Background technique [0002] With the development of mobile Internet, terminals and network devices have become an indispensable part of social life, and user information security and privacy protection are getting more and more attention. Moreover, the flat wireless network architecture, the full Internet Protocol (IP) of mobile networks, the intelligentization of terminals, and the miniaturization of the physical form of network equipment such as base stations have made terminals or network equipment vulnerable to more and more security threats. . [0003] In response to this threat to the security of the software and hardware of the terminal or network equipment itself, many terminals or network equipment require a certain trusted environment in design to verify the identity of the terminal or network equipment itself and wheth...
