Firefly is a U.S. National Security Agency public-key key exchange protocol, used in EKMS, the STU-III secure telephone, and several other U.S. cryptographic systems. References [ edit ]
FIREFLY is an NSA key management system based on public key cryptography. At least one commercial grade implementation uses Diffie-Hellman key exchange. STEs use security tokens to limit use of the secure voice capability to authorized users while other SCIP devices only require a PIN code, 7 digits for Type 1 security, 4 digits for unclassified.
A Type 1 Product refers to an NSA endorsed classified or controlled cryptographic item for classified or sensitive U.S. government information, including cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed.
As a "paperless encryption key system" OTAR was originally adopted specifically in support of high speed data communications because previously known "paperless key" systems such as supported by Diffie-Hellman key exchange, [3] or Firefly key exchange technology [4] (as used in the now obsolete STU-III "scrambled" telephone) [5] were not ...
FIREFLY key - (NSA) keys used in an NSA system based on public key cryptography. Key derivation function (KDF) - function used to derive a key from a secret value, e.g. to derive KEK from Diffie-Hellman key exchange. [citation needed] key encryption key (KEK) - key used to protect MEK keys (or DEK/TEK if MEK is not used).
The Electronic Key Management System (EKMS) is a United States National Security Agency led program responsible for Communications Security key management, accounting, and distribution. Specifically, EKMS generates and distributes electronic key material for all NSA encryption systems whose keys are loaded using standard fill devices, and ...

BATON is a block cipher developed by the NSA with a block size of 128 bits and key size of 320 bits. [citation needed] FIREFLY, on the other hand, is a key distribution protocol developed by the NSA. The FIREFLY protocol uses public key cryptography to exchange keys between two participants of a secured call.
