Send TEK to Other NCSs Using MK Method of OTAR (Special NCS Task 3)

6.4e.

This procedure allows an NCS to transfer a TEK (not a KEK) electronically,

DESCRIPTION

over-the-air-rekey (OTAR) to other NCSs. This capability IS useful

when the tactical situation or terrain makes it impossible or impractical

to pass new TEK by physical connection of ANCD to ANCD. Receiving

NCSs store the new TEK in their ANCDs. The new TEK can then be

passed to operators by physical transfer. Special NCS Tasks 3 and 5

are performed together by Source and Target NCSs, respectively.
