Abstract

This embodiment of the invention provides a protection method of chip and chip itself. The method includes: encrypting security verification information of software stored in chip by means of chip add principle to prevent the modification of the mentioned software security verification information; verifying the security of the mentioned software package stored in the chip by employing the software security verification information as soon as the single plate is connected to power. The technical proposal of this invention can guarantee the security of software verification information, effectively solve the problem of modification of chip contents, and also effectively assure the security of software that is operated on the single plate.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic equipment, and in particular, to a chip security protection method and the chip. Background technique [0002] A chip such as a Flash chip is a common component used in various electronic devices. For example, the Flash chip can be applied to a network element such as a wireless access point (Access Point; hereinafter referred to as AP). [0003] In the various electronic devices of the chip, various files can be pre-written in the chip to run when it is used. In the prior art, the content written in the chip can be read by special software, and after the content of the chip is read, it can be tampered with by disassembly technology. For electronic devices such as wireless APs with single-board chips, they are used as a bridge for home and home office (Small Office Home Office; Such electronic equipment requires higher security than large base station equipment. Ho...
