MYK-85 Key Management Unit

Types 1 and 3 Encryption/Decryption
Type 1 Commercial Hash Key Generation and Exchanges

The MYK-85 Key Management Unit cryptographic engine performs Type 1 and Type 3 data encryption and decryption, Type 1 Hash, commercial hash (SHA-1), key generation and exchanges, and other associated cryptographic functions. Designed and programmed by Mykotronx, Inc., the MYK-85 features a complete 32-bit RISC-based cryptographic processor. The Type 1 government encryption/decryption algorithm, called “Baton”—as well as DES and Triple DES—is in hardware. The MYK-85 also implements NIST Digital Signature and Secure Hash Standard.
