Abstract

The disclosure provides an encryption method, decryption method, device and processing equipment for proprietary information. The encryption method includes: when encrypting the proprietary information of the device, generating a first-type secret key and a second-type secret key; applying the first-type secret key to encrypt the proprietary information; applying the second-type secret key to encrypt the first Class key encryption; encrypt the second class key through the trusted security module preset in the device; store the encrypted first class secret key and the encrypted second class secret key. Through the present disclosure, the difficulty of obtaining proprietary information can be improved, and the security of proprietary information can be better guaranteed.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to an encryption method, decryption method, device and processing equipment for proprietary information. Background technique [0002] In order to distinguish devices, device manufacturers usually store proprietary information of the device in the storage medium of the device, so that the identity of the device can be determined by querying the proprietary information during production and after-sales. Among them, the proprietary information may be serial number, product model, production date, MAC address and other characteristic information that can be distinguished from other devices. [0003] However, the proprietary information of the device is easily obtained and tampered with illegally. For example, criminals can intercept the communication signal of the device hardware through a proprietary testing instrument, and then obtain the proprietary information of the dev...
