key translation center
(I) A type of key center (used in a symmetric cryptography) that
implements a key distribution protocol to convey keys between two
(or more) parties who wish to communicate securely. (See: key
distribution center.)
(C) A key translation center translates keys for future
communication between Bob and Alice, who (a) wish to communicate
with each other but do not currently share keys, (b) each share a
KEK with the center, and (c) have the ability to generate or
acquire keys by themselves. Alice generates or acquires a set of
keys for communication with Bob. Alice encrypts the set in the KEK
she shares with the center and sends the encrypted set to the
center. The center decrypts the set, reencrypts the set in the KEK
it shares with Bob, and either sends that encrypted set to Alice
for her to forward to Bob, or sends it directly to Bob (although
direct distribution is not supported in the ANSI standard
[A9017]).
