Embedded software encryption registration method combining with embedded equipment

Abstract

The invention discloses an embedded software encryption registration method combining with embedded equipment. According to the method, embedded software and the core processing unit ID of connected embedded equipment are bonded, the core processing unit ID and time of the embedded equipment are taken as encrypted parameter variables, registration is conducted by using an Rijndael algorithm in anaes algorithm to generate registration codes, secondary packaging encryption is conducted on the generated registration codes and the core processing unit ID of the embedded equipment to prevent errors in the mutual transmission process of the registration codes, the registration encryption of the embedded software is achieved, the normal, safe and reliable operation of the embedded software is ensured, malicious decryption on management software of a malicious opponent is effectively prevented, and the loss of an original producer is reduced.

Description

technical field [0001] The invention relates to the technical field of an encryption method, in particular to an embedded software encryption registration method combined with an embedded device. Background technique [0002] At present, some industries use online monitoring, online monitoring and other technological and informational means to manage, which improves the management level and reduces and eliminates losses caused by improper management. However, these technological and informational means such as online monitoring and online monitoring are all It is inseparable from the corresponding hardware products and management software. The R&D costs of the relevant manufacturers to develop these high-stability and reliable hardware products are very high. However, some competitors will crack these products of the same industry in order to save effort. Some users are willing to use cracked products in order to save costs, which often causes great losses to the original ma...

[0002] At present, some industries use online monitoring, online monitoring and other technological and informational means to manage, which improves the management level and reduces and eliminates losses caused by improper management. However, these technological and informational means such as online monitoring and online monitoring are all It is inseparable from the corresponding hardware products and management software. The R&D costs of the relevant manufacturers to develop these high-stability and reliable hardware products are very high. However, some competitors will crack these products of the same industry in order to save effort. Some users are willing to use cracked products in order to save costs, which often causes great losses to the original manufacturers. In order to prevent this phenomenon, many manufacturers will use encryption methods to prevent products from being cracked

[0003] At present, most manufacturers use a relatively simple encryption method. When the user changes the system time, the encryption method may be destroyed, resulting in cracking. A few manufacturers use relatively simple hardware encryption, such as: switching buses, using alternative RAM, using GAL devices, and encrypting the software in the EPROM outside the device, this does increase the difficulty of cracking the product to a certain extent, but overall the product is still more likely to be cracked, and the encryption effect is not ideal
