The recent book *Security for Computer Networks: An Introduction to Data Security in Teleprocessing and Electronic Funds Transfer*, by D.W. Davies and W.L. Price (New York: John Wiley & Sons, 1984) has a section on commercially available DES hardware (from the TOC): 3.6 Implementations of the Data Encryption Standard 76 Single Chips 77 Multiple-chip sets 78 Microprocessor implementations 78 Circuit boards for the DES 79 Tamper-resistant security modules 80 They give manufacturers, data rates, modes of operation, processors they are designed for use with, etc. Sorry, no prices. It's only worth it if you need the speed or the transparency. Some of the devices inmplement rudimentary key management functions as well. -- Richard Outerbridge 416 961-4757 Payload Deliveries: N 41 39'36", W 79 23'42", Elev. 106.47m.
