Problems solved by technology

[0004] 1. The registration code file is not encrypted and stored in the device, so it can be copied to other devices in plain text, so that the software installed on other devices can be illegally cracked
In addition, the content of the registration code file may be tampered with by the user to illegally extend the number of times of use or the validity period of the software
[0005] 2. The registration code file is not bound to the device, so the registration code file can be used in different devices, and the software installed on other devices is illegally cracked
[0006] 3. When the server transmits the registration code to the device, the content of the registration code file is not encrypted, which makes the registration code file easy to be monitored or forged

Abstract

The invention discloses an activation method of a trusted execution environment, the trusted execution environment is deployed in a terminal device, and the method comprises the following steps: sending a terminal device identifier to a server; receiving activation information returned by the server, the activation information comprising an encrypted trusted identity identifier, a trusted key andan activation code, the trusted identity identifier and the trusted key corresponding to the terminal device identifier, and the activation code being generated according to the terminal device identifier; decrypting the activation information to obtain a trusted identity, a trusted key and an activation code; and encrypting and storing the trusted identity, the trusted key and the activation codeinto a secure storage space. The invention also discloses an activation verification method of the trusted execution environment, an application activation and activation verification method based onthe trusted execution environment, and a corresponding device.

Description

Technical field [0001] The present invention relates to the technical field of application security, in particular to an application activation method and device based on a trusted execution environment. Background technique [0002] After the software is released, a way is needed to prevent the software from being cracked and misappropriated to ensure the software developers' own interests. Currently, the software is usually protected by a registration code, that is, the user first downloads and installs the trial version of the software, and then activates the software by applying for the registration code from the server. Later, when the user uses the software, the software will read the registration code file and determine whether the software is available according to the registration code file. [0003] There are some problems with the above software activation scheme: [0004] 1. The registration code file is not encrypted and stored in the device, so that it can be copied t...
