FOREWORD ITU (International Telecommunication U

8、nion) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. Some 179 member countries, 84 telecom operating entities, 145 scientific and industrial organizations and 38 international orga

9、nizations participate in ITU-T which is the body which sets world telecommunications standards (Recommendations). The approval of Recommendations by the Members of ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, 1993). In addition, the World Telecommunication Standard

10、ization Conference (WTSC), which meets every four years, approves Recommendations submitted to it and establishes the study programme for the following period. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with

11、 IS0 and IEC. The text of ITU-T Recommendation X.217, Amendment 1, was approved on 5th of October 1996. The identical text is also published as ISO/IEC International Standard 8649. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunicati

16、n to identify ACSE user requirements. Two functional units are defined: a) Kernel functional unit; and b) Authentication functional unit. The Kernel functional unit is always available. The Authentication functional unit supports peer entity authentication. This functional unit does not include addi

17、tional services. It adds parameters to the A-UNIT-DATA service. Table 2 bis shows the services and parameters associated with the ACSE functional units for the connectionless mode of communication.

If it is not present, only the Kernel functional

21、 unit is requested. This parameter takes on the following symbolic value: - authentication. 9.5.1.16 Authentication-mechanism Name This parameter shall only be used if the ACSE Requirements parameter includes the Authentication functional unit. If present, the value of this parameter identifies the

22、authentication-mechanism in use. If not present, the communicating AEIs must implicitly know the mechanism in use (e.g. by prior understanding). 9.5.1.17 Authentication value This parameter shall only be used if the ACSE Requirements parameter includes the Authentication functional unit. If present,

23、 this parameter contains an authentication-value generated by the authentication-function in the AEI that issued the service primitive. It is intended for the peers authentication-function. 3) Subclause 9.5.1, Table 7 Add the following rows to the end of Table 7: I Authentication value 2 ITU-T Rec.
