SAVILLE is an NSAType 1encryption algorithm. It is used broadly, often for voice encryption, and implemented in a large number of encryption devices. Little is known publicly about the algorithm itself. Some documentation related to the KYK-13fill device and statements made by military officials suggest that SAVILLE has a 128-bit key. On the AIMmicrochip, it runs at 4% of the clock rate (compare DES at 76% and BATON at 129%). The Cypris chip mentions 2 modes; specifications for Windster and Indictor specify that they provide Saville I. Some devices and protocols that implement SAVILLE:
