Problems solved by technology

However, at present, most of the production equipment of OEM manufacturers do not have networking functions, which makes it impossible to implement online activation solutions for production equipment.
[0006] In the offline activation solution, the OEM manufacturer enters the activation code provided by the brand into the production equipment. However, during the activation process, the activation code may be accidentally damaged or lost, resulting in the subsequent unusability of the production software.

Abstract

The embodiment of the invention provides a trusted execution environment activation method and device, the trusted execution environment is configured in equipment, and the equipment is further configured with a trusted application program running in the trusted execution environment, a rich execution environment and a client program running in the rich execution environment; the method comprisesthe following steps of enabling the trusted execution environment to acquire an activation file which is sent by the client program and is preset in the equipment; enabling the trusted execution environment to verify whether the activation file is legal or not; if the activation file is legal, activating the trusted execution environment and allowing the trusted application program to run normally; and after the trusted execution environment is activated, storing the activation file into a trusted storage space of the equipment. In the embodiment of the invention, the equipment can be activated without depending on a network.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a trusted execution environment activation method and a trusted execution environment activation device. Background technique [0002] OEM production refers to the way that brand owners entrust OEM (Original Equipment Manufacturer) manufacturers for processing and production. [0003] In order to prevent illegal production by OEMs, brand owners can authorize and monitor the production equipment of OEMs. The brand owner can install the production software that needs to be activated by the brand owner on the production equipment of the OEM manufacturer, and the production process of the equipment is controlled by the production software. [0004] At present, the activation mode of the production equipment of the OEM manufacturer may include an online activation scheme and an offline activation scheme. [0005] The online activation solution requires the production e...
