NSA Encryption Systems

NSA is responsible for the encryption-related components in these systems:

• EKMS Electronic Key Management System
• FNBDT Future Narrow Band Digital Terminal
• Fortezza encryption based on portable crypto token in PC Card format
• KL-7 ADONIS off-line rotor encryption machine (post-WWII – 1980s)
• KW-26 ROMULUS electronic in-line teletypewriter encryptor (1960s–1980s)
• KW-37 JASON fleet broadcast encryptor (1960s–1990s)
• KY-57 VINSON tactical radio voice encryptor
• KG-84 Dedicated Data Encryption/Decryption
• SINCGARS tactical radio with cryptographically controlled frequency hopping
• STE secure terminal equipment
• STU-III secure telephone unit, currently being phased out by the STE
• TACLANE product line by General Dynamics C4 Systems

NSA has specified Suite A and Suite B cryptographic algorithm suites to be used in U.S. government systems; the Suite B algorithms are a subset of those previously specified by NIST and are expected to serve for most information protection purposes, while the Suite A algorithms are secret and are intended for especially high levels of protection.
