This document has been submitted to APCO/NASTD/FED by the Telecommunications Industry Association (TIA), as provided for in a Memorandum of Understanding (MOU) dated December,

34、 1993. That MOU provides that APCO/NASTD/FED will devise a Common System Standard for digital public safety communications (the Standard), and that TIA shall provide technical assistance in the development of documentation for the Standard. This document has been developed by TR8.3 (Encryption) with

35、 inputs from the APCO Project 25 Interface Committee (APIC), the APIC Encryption Task Group, and TIA Industry members. This document is being published to provide technical information on the emerging digital techniques for Land Mobile Radio Service. TIA-102.AACE-A iv Patent Identification The reade

36、rs attention is called to the possibility that compliance with this document may require the use of one or more inventions covered by patent rights. By publication of this document no position is taken with respect to the validity of those claims or any patent rights in connection therewith. The pat

37、ent holders so far identified have, we believe, filed statements of willingness to grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such licenses. The following patent holders and patents have been identified in accordance wi

38、th the TIA intellectual property rights policy: No patents have been identified. TIA shall not be responsible for identifying patents for which licenses may be required by this document or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.

39、IA-102.AACE-A 1 1 INTRODUCTION Authentication of subscriber units is a vital component of a general land mobile radio system. The purpose of this document is to define a Challenge and Response Authentication method for use on trunked radio systems. 1.1 Scope The authentication service described in t

40、his document is applicable to FDMA and TDMA trunking systems using an FDMA trunking control channel. Authentication is a supplementary service for trunked radio systems. This document describes two forms of authentication: unit authentication and mutual authentication. If unit authentication is impl

41、emented it shall be implemented as specified herein. If mutual authentication is implemented , it shall be implemented as specified herein. This document defines the full standard across the Uminterface. 1.2 Document Description This document describes Challenge and Response Authentication designed

42、to protect the family of Project 25 systems. Section 1 provides a general description, definitions and abbreviations. Section 2 provides high-level information about Challenge and Response Authentication. Section 3 provides procedures and operational descriptions. Section 4 provides a listing of con

43、trol channel messages Section 5 provides information on key management and provisioning. Section 6 provides algorithm details.

45、document. Moved Provisioning File Format to Security Services Provisioning document. Added that the interface between SU and Provisioning will be specified by the Key Fill standard. Added example state diagrams for authentication that also provides context for error cases. August 4, 2004 Revision 5,

46、 updated based on NCS and M/A-COM comments. September 16, 2004 Revision 6, updated based on September 13, 2004 Encryption Task Group meeting. January 31, 2005 Revision 7, added MSC for subscriber initiated authentication demand, modified message returned from the RFSS on authentication failure and f

47、ixed typographic errors. March 8, 2005 Revision 8, fixed typographic errors, corrected AM2 and AM4 sample data, segmented out informative references and removed Annex A Control Channel Messages.

AES has a 128 block size and AES-128 indicates that a 128 bit key is used with AES as described in referenc

49、e 2. Adversary FNE A FNE that is not a valid FNE. Adversary SU A SU that is not a valid SU. Authenticated SU A SU whose SUID has passed a challenge and response authentication. This SU has proven that it is the valid SU. Authentication The process to prove that a SU is valid. Authentication Facility (AF) A functional process within the FNE. It is being included in order to show the specialized functions that the FNE must implement in order to support authentication. Such functions include assignment of K to SUID, generation of KS and KS using RS to allow th
