Their purpose is to ensure that a PB built accordi

15、ng to this standard can communicate with any ACRE manufactured according to this standard. Conversely, these technical requirements ensure that an ACRE manufactured according to this standard can communicate with any PB built according to this standard. These requirements do not address the quality

16、or reliability of this service, nor do they cover equipment performance or measurement procedures. To ensure compatibility, it is essential that both physical layer parameters and call-processing procedures be specified. Physical layer parameters are described in detail for both the PB and the ACRE.

17、 Detailed call-processing procedures are specified for the PB to ensure a uniform response to all ACRES. Call-processing procedures are described in less detail for the ACRE to allow more latitude in system design. Authentication procedures in this Standard incorporate processes described in TIA Com

18、mon Cryptographic algorithms, revision B (the distribution of this document is controlled be the TIA). These technical requirements have been organized into four sections. The following is a summary of each section: 1. Introduction. This section comprises a list of brief explanations of terms, proce

19、sses, and functions used in these requirements. Since it is the intention of these requirements to permit great latitude of system configurations and the implementation of system features, only those items required for compatibility have strict definitions. 2. Personal Base Compatibility Requirement

20、s. This section comprises the fundamental signaling compatibility requirements of the PB. If strictly adhered to, the PB technically will be able to signal an ACRE. In general, changes or alterations to this section will affect fundamental PB - ACRE compatibility and the ability of the PB to signal

21、an ACRE irrespective of signaling conditions. 3. ACRE Compatibility Requirements. This section comprises the fundamental signaling compatibility requirements of the ACRE and is organized in a manner similar to 2. (In fact, 2 and 3 should be read together for a clearer understanding of the bi-directi

22、onal signaling protocol.) If strictly adhered to, an ACRE technically will be able to signal a PB. In general, changes or alterations to this section will affect fundamental PB - ACRE compatibility and the ability of the PB to signal an ACRE irrespective of signaling conditions. 4. Change History. T

23、his section traces all changes to these technical requirements beginning with the initial release of this standard. A brief description of each change as well as a reference to the affected section(s) is provided. EIA TIAIIS-680 9b W 3234600 0573484 835 W 1 2 3 4 5 6 r 8 9 10 11 12 13 14 15 16 ir le

38、 number that uniquely identifies an MS to a cellular system. See ELMA IS-91A for details on the format for the Electronic Serial Number for MSs. 2.2.4 Authentication Authentication is the process by which infomtion is exchanged between the PB and the ACRE for confrming the identity of both the PB an

39、d the ACRE. A successful outcome of the authentication process occurs only when it can be demonstrated that the PB and ACRE possess identical WMEY values. 2.2.4.1 Wireline Interface Key (WIKEY) WKEY is a 64-bit pattern stored in the PB and the ACRE (in semi-permanent memory). It is stored in the PB

40、during the manufacturing process. The WMEY shall not be capable of being displayed or altemi by the user. It is provided to system operators at the time of manufacture. WMEY may be changed during the WMEY update process (see 2.2.4.7). If WIKEY is modified, it is the responsibility of system operator

41、 to securely transfer the WMEY to the new system operator in the event that the PB moves from one system to the next. 10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 n 18 19 P n P 31 22 Country Code EIA TIA/IS-bO 96 U 3234b00 057L49b 537 TIA/EIA/IS-680 21 65 O Network Code Subnet Code 2.2.4.2 Random varia

42、bles There are three types of random variables utilized during the authentication process. These random variables are as follows: RAND-ACRE - This field contains a 32-bit random number generated by the PB. It is utilized in the calculation of ACRE Authentication Result to determine if the ACRE conta

43、ins a correct value for WMEY. W-PB - This field contains a 32-bit random number generated by the ACRE. It is utilized in the calculation of PB Authentication Result to determine if the PB contains a correct value for WIKEY. W-WIKEY - This field contains a 56-bit random number generated by the ACRE.

44、It is utilized in the calculation of a new value for =Y. 2.2.4.3 Authorization Count (AUTH-COUNT) AUTH-COUNT is a modulo-64 counter held in the PB and the ACRE. It is updated every time the PB successfully performs an Authorization. It is utilized by the ACRE to detect cloned PBs. 2.2.4.4 ACRE Ident

45、ification (ACREJD) ACRE-ID I The Country Code indicates the country where the ACRE is located. The Country Code is set to zero at the time of manufacture. The Network Code allocation is shown in Table 2.2.4.4-1. The Subnet Code allows system operators to utilize multiple ACRES per System Identificat

46、ion (SID).

Whenever an ACRE performs a WIKEY update it sends the value corresponding to the system in which it reside

48、s. These values are for use by PB manufacturers. The least significant 8 bits of these values correspond to the manufacturer code contained in the PBID. The PB manufacturer sets the Network Code at the time of manufacture to the value containing the PB manufacturers manufacturer code. Reserved 2.2.4

49、5 Calculation of PB Authentication Result PB Authentication Result shall be calculated during the Authorization process to ensure that the ACRE is connected to a legitimate PB. The procedure is as follows: At the ACRE, AtthePB, send RAND-PB to the PB in the Connect message. set the input parameters of the Wireiine Interface Authentication Signature Calculation Procedure; execute the Wireline Interface Authentication Signature Calculation Procedure (refer to Common Cryptographic Algorithms, Revision B); set PB-Am-RESULT equal to the 18-bit output AUTH-SIGNATURE;
