security publications. Thus the Air Force Communications Security
Manual 2, formerly known as AFCOMSECM-2, is now listed as AFKAG-2.
COMSEC prepares courses of instruction for new cryptographic equipment
and issues regulations for its operation, presumably mandating such
matters as the when and how of primary and secondary key changes. For
interdepartmental and presidential communications, it probably
produces the keys—rotor wirings, lists of positions, one-time tapes. Keys
for communications wholly within, say, the Air Force are presumably
produced by its own cryptographic agencies.
COMSEC, drawing upon R/D's STED, devises new systems
of encipherment and embodies them in new mechanisms. It works
closely with potential users, such as the State Department, to make sure
that the equipment fits the user's needs and at the same time provides
adequate security
