Abstract

The invention provides a wireless device firmware encryption system used by an embedded device to generate a ciphertext to avoid being baked. The system comprises a cloud server and a computer end. The cloud server stores a legitimate media access control address to a database. The computer end is connected to the cloud server in an internet manner, and is connected to the embedded device via a universal sequence bus or other connection lines, so that the embedded device sends a Wi-Fi media access control address to the cloud server via the computer end, the cloud server generates a ciphertextvia the Wi-Fi media access control address, and the computer end burns the ciphertext in the embedded device.

Description

technical field [0001] The present invention relates to an encryption method, in particular to a wireless device firmware encryption method, in which a pure software encryption method is used to protect the embedded device and prevent the embedded device from being copied. Background technique [0002] The advancement of technology has made people's lives full of embedded devices or embedded systems, especially today's embedded devices can be said to be used in various fields such as consumer, cooking, industry, automation, medical, commercial and military. Examples include MP3 players, mobile phones, game consoles, GPS receivers, automobiles, electric vehicles, electronic stethoscopes, and surveillance equipment. The structure of embedded equipment is mainly composed of embedded processors, related supporting hardware and embedded software systems. It is a "device" that integrates software and hardware and can work independently. Embedded processors are mainly composed of ...
