Association of Public Safety Communications Officials (APCO) Project 25 Over The Air Re- keying (OTAR) Protocol [TIA TSB 102.AACA]

This document directly addresses methods of over the air re-keying (OTAR) and closely associated over the air key management functions in a multi-key APCO Project 25 system. The primary objective of this document is to enable subscriber units and systems that conform to this document to be interoperable to the extent that keys can be passed via the common air interface (CAI) between communicating units and encrypted communications can result. This is accomplished by sending key management messages over the air with the CAI functions defined for OSI (Open Systems Interconnection -- Reference Model) layers 1 and 2. The keys which are required for the encryption algorithms can be distributed over the air rather than manually.
Other Standards: This document relates to TSB 102A, "Project 25 System & Standard Definition" and others in the Project 25 series.
