阐述了一种信息安全芯片的设计思想。芯片的设计是面向功能模块的,而不是面向应用的。通过可选的集成的USB接口或并行FIFO,上层应用软件可以如同调用的标准应用函数来调用芯片的各功能模块,替换应用软件中软件加密模块,改善系统安全性能和提高加解密速度。
Describes a design of information security chip. The design of the chip is for functional modules, not for application. Through the optional integrated USB interface or parallel FIFO, the upper application software can invoke the function modules of the chip as the called standard application function, and replace the software encryption module in the application software to improve the system security performance and increase the encryption speed.
