据《Electronic Design》1985年1月刊报道:美国加利福尼亚州西部数字公司推出的一种最快且行之有效的加密器件——WD2200数据保密板允许个人计算机用户控制或禁止对数据文件的访问。基于ALBS认可的WD2001数据加密片的板子可以1.3Mb/s的数据传送速率工作。为了IBM PC和PC兼容的计算机应用而设计的这种MD2200器件能自动地对数据进行加密和解密,而对应用软件却保持透明的状态,并能在软、硬磁盘和磁带上对数据加以保护。
According to Electronic Design’s January 1985 issue: Western Digital, California, USA, one of the fastest and proven encryption devices, the WD2200 Data Security Board allows PC users to control or block access to data files. The board based on ALBS approved WD2001 data encryption chip can work at 1.3Mb / s data transfer rate. Designed for IBM PC and PC-compatible computer applications, this MD2200 device automatically encrypts and decrypts data while keeping applications transparent and protecting data on both hard and soft disks.
