Send TEK to Net Operators Using AK Method of OTAR(Special NCS Task 4)

This procedure enables an NCS to transfer electronically a TEK (not a

DESCRIPTION

KEK) directly from the NCS ANCD to net member radios. In the AK

method, the TEK transferred to net member radios automatically, and

instantaneously, replaces the TEK being used. Also, the KEK in net

member radios is automatically updated (changed) during the AK

procedure. After sending a TEK by AK OTAR, the Source NCS must

load the new TEK. While the AK method of OTAR requires no action on

the part of receiving net members, it is quite demanding of the Source

NCS.
