据《Digital Design》1986年8月刊报道:哈里斯半导体公司推出的HS3447Cypher Ⅰ器件能代替数据加密标准设备。该器件的数据速率高达20Mb/s,它采用了NSA算法,能对串行的数据流进行加密和解密,可用在标准的数据加密中,但也可以用在扩频通信中。本产品质量可靠,以千个为单位批量出售时,每器件的售价为80美
According to Digital Design, August, 1986, the HS3447Cypher I device from Harris Semiconductor replaces data encryption standard devices. The device’s data rate of up to 20Mb / s, which uses the NSA algorithm, the serial data stream can be encrypted and decrypted, can be used in standard data encryption, but also can be used in spread spectrum communications. The quality of this product is reliable, with thousands of units sold in bulk, the price of each device is 80 US dollars
