11.4.4 Key Management Facility
The Key Management Facility (KMF) provides key management and OTAR functions to
applicable radios within the radio system. One of the main tasks of the KMF is to maintain
a data base of information contained in each radio. This information may include the
following:
• TEKs (main Traffic Encryption Keys)
• KEKs (Key Encryption Keys) used to encrypt OTAR messages
• Keysets (groups of TEKs or KEKs)
• Crypto groups (groups of keysets)
• Cryptonets (groups of radios using same keys)
• Individual and group Radio Set Identifiers (RSIs)
• List of probable lost or stolen radios
The KMF performs OTAR functions by exchanging Key Management Messages (KMMs)
with the radios. Both the KMF and radio can originate messages. Some functions
performed by the KMF are as follows:
• Loading new keys
• Modifying keys
• Initiating keyset switch overs
• Modifying keyset attributes
• Deleting one or more keys to remove a radio from a cryptonet)
• Deleting all keys (zeroize) when a radio may be lost or compromised
• Determining if a radio is on the air and reading key information
• Changing individual and group RSIs
