印制电路板的防抄板技术及实现方法

Anti-copy board technology and implementation of printed circuit boards

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 the designer must be printed circuit board to do high precision, high density and high reliability,this is a big chall-enge to designers.At the same time,the development of hacking and anatomy of the chip technology,allows embedded systems are facing more and more attacks.With raw copy board technology has also caused the attention of the product designers.The artic-le puts forward the prevent printed circuit board hardware copy plate measures and the realization method of the core chip encryption,can be very effective to deal with all kinds of copy board problem.
