Encryption protection method for single-chip microcomputer software and storage medium

Abstract

The invention belongs to the technical field of single-chip microcomputer safety. The invention particularly provides an encryption protection method for single-chip microcomputer software and a storage medium. The method comprises the following steps: randomly generating multiple groups of original passwords, calculating a check value of each group of original passwords by using a hash function,performing multiple groups of hash operations on each group of original passwords to obtain HASH1, performing symmetric encryption on the HASH1 to obtain CODE1, and burning and inputting the originalpasswords, the check values and the CODE1 into a fixed storage area of a single chip microcomputer; then presetting and storing an independent UID, performing operation on the checked original password by using a plurality of hash functions to obtain HASH1, adding an independent UID to the HASH1, performing hash operation again to obtain HASH2, performing symmetric encryption on the HASH2 to obtain CODE2, and writing the CODE2 into a region position of the original password in a covering manner; and finally, randomly accessing each group of CODE1 and corresponding CODE2 data, and performing legal copy verification through calculation. According to the scheme, encryption protection of single-chip microcomputer software with an application programming function is supported, and whether software operated by a single-chip microcomputer is a legal genuine version or not is verified by using an independent UID and an original password of the single-chip microcomputer or a peripheral chip andthe like.

Description

technical field [0001] The invention belongs to the technical field of single-chip microcomputer security, and in particular relates to an encryption protection method and a storage medium of single-chip microcomputer software. Background technique [0002] Application programming is IAP, which is the acronym for In Application Programming. IAP is the programming of some areas of User Flash by the user's own program during the running process. The purpose is to conveniently pass through the reserved communication port after the product is released. Update and upgrade the firmware program in the product. [0003] The development of single-chip microcomputers is very rapid, from 51-core single-chip microcomputers, to 8-bit machines, 16-bit machines, and 32-bit machines with private instruction sets introduced by various manufacturers, to general-purpose ARM core single-chip microcomputers, and then to open-source instruction set RISC-V architecture single-chip microcomputers ...
