Mainboard hardware and upper software encryption-decryption and recognition method based on single-chip microcomputer

Abstract

The invention discloses a mainboard hardware and upper software encryption-decryption and recognition method based on a single-chip microcomputer, which is used for judging the credibility of remote hardware to access a host. The method comprises the following steps of 1) formulating encryption and decryption algorithms between a mainboard of the host and the remote hardware of a slave; 2) encrypting hardware information of the mainboard through the encryption algorithm, and storing the encrypted hardware information in a local carrier; 3) transmitting the encrypted hardware information of themainboard to the remote hardware; 4) receiving the encrypted hardware information of the mainboard by the remote hardware, decrypting the hardware information through the decryption algorithm, and transmitting decrypted data to the host; and 5) performing comparison and verification on the decrypted data transmitted by the remote hardware and stored data by the host, and judging the credibility of the remote hardware through a verification result. According to the method, the encryption and decryption algorithms are formulated between the host and the slave, and through the transmission and verification of the algorithms, the reliability of the remote hardware is judged, so that the security performance of the host is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an encryption, decryption and identification method for motherboard hardware and upper-layer software based on a single-chip microcomputer. Background technique [0002] In the design of hardware circuits, discrete components (resistors and capacitors, etc.) cannot be accessed by programs, so in the process of remote communication and interaction, local programs cannot know whether the remote hardware is trustworthy, and hardware changes, attacks or even Destruction is impossible to understand. At this time, a carrier that is responsible for storing the current hardware information locally is needed, and this information is stored and transmitted in an encrypted manner. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method for encryption, decryption and identification based on ...
