基于FPGA的单片机系统总线保密技术

Security Technology on FPGA Single-chip Computer's Bus

目前,单片机应用已十分广泛,其系统的保密技术也多种多样,但大都能被轻易破解,给开发者带来不必要的损失,因此,系统的防泄密功能显得至关重要．对基于FPGA的单片机系统总线保密技术进行了深入探讨,以期为单片机系统设计与开发提供指导和帮助．

At present, the single-chip computer is used widely. Though there are various types of security technology to protect system, they are easy to be decoded, which constitutes an unnecessary loss to the developers＇, Therefore, it＇s of the utmost importance for the computer system to have precautions against divulgence, This paper seeks a new kind of security technology used to protect single-chip computer＇s bus based on FPGA and provides fifteen plans of combinatorial security technology, which will be able to be applied to designing and developing the computer systems, and provide the developers＇ interests with effective protection as well.
