嵌入式系统的快速发展要求设计者必须将印制电路板做到高精度、高密度和高可靠性,这对设计者是一个很大的挑战。与此同时,黑客技术的迅速发展与芯片解剖技术的逐渐成熟,使得嵌入式系统所面临的各种攻击也越来越多,随之而生的印制电路板抄板技术也很快的引起了广大电路板设计者的重视。文章提出的印制电路板硬件的防抄板措施以及其核心芯片加密的实现方法,可以非常有效的应对各类抄板问题。
The rapid development of embedded systems requires designers to be printed circuit board to achieve high accuracy, high density and high reliability, which is a great challenge for the designer. At the same time, the rapid development of hacker technology and the gradual maturity of the chip anatomy technology, making the embedded systems are facing more and more attacks, the resulting printed circuit board copy technology also quickly caused The majority of circuit board designers attention. The article puts forward the printed circuit board hardware anti-copy board measures and its core chip encryption method can be very effective in dealing with various types of copy board problems.
