Secure chip burning method and system

Abstract

The invention provides a secure chip burning method and system. The invention discloses a secure chip burning method. The method specifically comprises the following steps: checking a test machine; reading unique information data of the tested chip; performing encryption calculation on the unique information data of the tested chip according to a preset encryption algorithm to obtain an exclusive digital certificate corresponding to the tested chip; and burning the exclusive digital certificate on the tested chip through the test machine. According to the method, the transmission link of the burnt content of the tested chip is shortened, the burnt content is obtained through calculation by an encryption algorithm after the unique information data of the tested chip is read, the whole data transmission is completely carried out in a hardware security environment, cross-hardware public network transmission is avoided, and the transmission efficiency is improved. The problem of leakage caused by separate distribution of the burnt content and the tested chip in the prior art is solved, and the method has high safety and high convenience and is suitable for batch production operation.

Description

technical field [0001] The invention relates to a chip programming method and system, in particular to a safe chip programming method and system, and belongs to the technical field of chip manufacturing. Background technique [0002] With social development and technological progress, the market demand for security chips continues to increase, expanding from the previous national defense security to many civilian markets. Many chips have security certification requirements, and keys need to be burned in the chip. However, the production of today's chips is basically carried out in the form of outsourcing, which means that the key needs to be distributed to the outsourcing factory through a secure channel, and then the chip is encrypted and burned through the test machine in the factory. This process involves many links, and security, convenience, and batch performance all face great challenges. [0003] In the prior art, key burning during the production and testing process...

Problems solved by technology

The disadvantages of the above methods are obvious. First, it is necessary to build a security server and a dedicated security communication network for secure transmission of encrypted files; second, a dedicated security terminal is required to decrypt and then upload the test program to the security server; third, every A test machine needs to send a request to the server to obtain the decrypted key data and download it to the chip under test; fourth, information security and confidentiality need to run through the entire generation, transmission, and download processes, and it is necessary to strictly ensure that the key data and product information control, undoubtedly increases the cost of management operations
