摘要
介绍了目前流行的加密算法规则及其应用领域。通过对DES算法的硬件实现,提出了一种通过IDE接口实现加密硬盘的方案,以及U盘的身份认证方案,为用户本地信息的安全性提供了双重保障,同时相对于用户操作透明,对机器性能无任何影响。该方案目前已经进入试验阶段,基本能够较好地解决用户硬盘保密性要求和用户身份认证的惟一性要求,以期向市场进一步推广。
The popular encrypt algorithms axe introduced in this paper. By a hardware realization of DES algorithm, a harddisk eneryption precept using the IDE interface is lodged as well as the identification precept using a USB disk, which can dually ensure the customers＇security in local information. At the same time, this precept is transparent for the users＇operation and it does nothing to the computer＇s capability. This precept has been in examination at the preset, and the result is that it can properly meet the request of the harddisk secret and the exclusive user identification. In the future, it will go to the market.
