> How fast are they? What do they cost?
Here's a bit more detail:
Called the Data Cipering Processors,
Am9518 - 3MHz version, Z8000-type bus interface
up to 1.3 Mbyte/s ciphering throughput
AmZ8068 - 4MHz version, Z8000-type bus interface
up to 1.7 Mbyte/s ciphering throughput
Am9568 - 4MHz version, 8086-type bus interface
up to 1.5 Mbyte/s ciphering throughput
The spiel from brochures:
Encrypts and decrypts data
Implements NBS standard data encryption algorithm
Throughput over 1.5M bytes per second
Operates at data rates fast enough for disk controllers
high-speed DMA, telecommunication channels
Supports 3 ciphering options
Electronic Code Book for disk applications
Cipher Block Chain for high-speed telecommunications
Cipher Feedback for low to medium speed byte oriented communications
3 separate key registers on one chip
Separate registers for encryption key, decryption key,
and master key
3 separate data ports provide flexible interface, improved security
Cost is about $30-$50, I believe.
