Abstract

The embodiment of the invention relates to an authority control method, authority control equipment, user equipment and a system. The method comprises the following steps: extracting a physical unclonable function value of user equipment; Setting a physical unclonable function value of the user equipment as a trust root; Encrypting a preset application in the user equipment; And generating and sending authority control information to the user equipment so as to authorize a preset application in the user equipment, cancel authorization for an authorized application in the user equipment or adjust an authorization range. According to the embodiment of the invention, the remote authority control system is established by taking the physical unclonable function value of the user equipment as the trust root, the security is high, and the flexibility is high.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an authority control method, authority control equipment, user equipment and a system. Background technique [0002] Currently, when manufacturers with core technology sell their products to downstream customers, they hope to protect the core technology information involved in their products because of the uniqueness of their technology. In the prior art, protection is often carried out by software means, for example, by inputting the authorization code on the packaging box to complete remote authorization; or by white box key or other software means for protection. However, due to its own limitations, this kind of approach is vulnerable to attacks and reverse code cracking. How to enhance the protection strength is a technical problem to be solved urgently in this field. Contents of the invention [0003] Embodiments of the present invention provide an a...
