TIA-102.AACD-A:2014

This document addresses the manual rekeying interface between a
KFD and an MR only. Although some system level overview is
provided, system level definition is not fully covered.

Purpose

This document describes the protocols, procedures, and features
for a manual rekeying function. Manual rekeying involves the
exchange of Key Management Messages between a KFD and an MR for the
purposes of provisioning an MR with encryption keys, authentication
keys or other key management related information, erasing keys in
an MR, or viewing key management related information in an MR.

Manual rekeying can be used as the sole means for provisioning
mobile radios with traffic encryption keys or it can be used in
conjunction with OTAR rekeying procedures. When used with OTAR
rekeying procedures, manual rekeying can be used to provision an MR
with key management parameters required for OTAR operation in
addition to provisioning encryption keys. Manual rekeying can also
be used for provisioning mobile radios with authentication
keys.
