Embedded microprocessor unclonable function secret key certification system and method

Abstract

The invention discloses an embedded microprocessor unclonable function secret key certification system. The embedded microprocessor unclonable function secret key certification system comprises an embedded terminal, a burning equipment terminal and a PC terminal. The embedded terminal comprises a PUF module for extracting data to be analyzed and an IAP module. The burning equipment terminal comprises a module for processing a program to be burned. The PC terminal comprises an embedded certification program generating module, a PUF analysis module, a database module, a hash data generating module and a help data generating module. The PUF module for extracting data to be analyzed is used for extracting primary power-on data in an SRAM repeatedly and transmitting the data to the PUF analysis module. The PUF analysis module is used for analyzing the collected primary power-on data and the size of the sample of the primary power-on data. The PUF analysis module is further used for transmitting an acquired secret key to the hash data generating module and the help data generating module. The embedded microprocessor unclonable function secret key certification system prevents an attacker from decrypting the secret key of embedded equipment through physical attack to copy the whole embedded software, and therefore the copyright of the embedded software is protected.

Description

technical field [0001] The invention belongs to the field of embedded system security, and more specifically relates to an embedded microprocessor non-clonable function key authentication system and method. Background technique [0002] In recent years, the demand for embedded devices in my country has surged. Under the temptation of huge profits, many enterprises abandon the traditional "R&D-production-sales" model and instead adopt the "imitation-production-sales" approach. The products developed by many companies with painstaking efforts are cracked by competitors shortly after they are put on the market. From hardware to software, they are completely cloned and put on the market after repackaging. There are also companies that entrust manufacturers to produce products, and the manufacturers additionally produce a large number of the same products and put them on the market under different brands. [0003] In this atmosphere of vicious imitation, a large number of compa...

Problems solved by technology

[0008] At present, the security products widely used in the industry lack independent intellectual property rights, and are relatively old and not safe enough

On the other hand, some advanced security products are restricted and expensive, and their use in our country is restricted
