一种加密算法的应用方案

摘要

The information and data security in the enterprise operations and daily life becomes more and more important. This paper focus on the design and implementation of encryption computer based on Loongson-2 Enhanced processor and T-DES encryption algorithm, which did not increase the cost of hardware and was transparent to the operating system. This design can encrypt and decrypt the hard disk data .%文章介绍了基于龙芯2号增强型处理器（以下简称龙芯2E）和T-DES加密算法的加密计算机设计方案，该方案可在不增加硬件成本并对操作系统透明的情况下，完成对硬盘数据的加解密。
