8、lecommunications. 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 organizations participate in ITU-T which is the body which sets world
9、 telecommunications standards (Recommendations). The approval of Recommendations by the Members of IT-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, 1993). In addition, the World Telecommunication Standardization Conference (WTSC), which meets every four years, approves
10、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 IS0 and IEC. The text of IT-T Recommendation X.835 was approved o
11、n 5th of October 1996. The identical text is also published as ISOAEC Intemational Standard 11586-6.

16、Security (GULS). It is the Protocol Implementation Conformance Statement (PICS) proforma for the Protecting Transfer Syntax Specification specified in IT-T Rec. X.833 I ISOAEC 11586-4 and the Security Transformation described in ITU-T Rec. X.830 I ISOAEC 11586-1, Annex D. This Recommendation I Inter
17、national Standard provides a description of the standardized capabilities and options in a form that supports conformance evaluation of a particular implementation. Introduction This Recommendation I International Standard forms part of a series of Recommendations I International Standards that prov
18、ide generic upper layer security services. The parts are as follows: 1) Overview, Model and Notation. 2) 3) 4) Protecting Transfer Syntax Specification. 5) 6) Security Exchange Service Element Service Definition.

19、ment Service PICS Proforma. Protecting Transfer Syntax PICS Proforma. This Recommendation I International Standard constitutes Part 6 of the series. Part 4 defines protecting transfer syntax for communications transfers between open systems as part of the operation of a security mechanism. To evalua
20、te the conformance of a particular implementation, it is necessary to have a description of the capabilities and options which have been implemented. Such a description is called a Protocol Implementation Conformance Statement (PICS). This Recommendation I International Standard includes the PICS pr
21、oforma for the protecting transfer syntax specified in Part 4 and the security transformations defined in Part 1, Annex D. . ITU-T Rec.

22、CTION - GENERIC UPPER LAYERS SECURITY: PROTECTING TRANSFER SYNTAX PROTOCOL IMPLEMENTATION CONFORMANCE STATEMENT (PICS) PROFORMA 1 Scope This Recommendation I Intemational Standard defines a Protocol Implementation Conformance Statement (PICS) proforma for the detailed expression of the conformance r
23、equirements of ITU-T Rec. X.833 1 ISOEC 11586-4 and hex D of ITU-T Rec. X.830 I ISOAEC 11586-1. This PICS proforma is in compliance with the relevant requirements, and in accordance with the relevant guidance for a PICS proforma, given in ITU-T Rec. X.291 and ISOAEC 9646-2. Detail of the use of this
24、 proforma is provided in this Recommendation 1 International Standard. Implementations claiming conformance to IT-T Rec. X.833 I ISOAEC 11586-4 or Annex D of IT-T Rec. X.830 I ISOAEC 11586-1 shall complete the proforma as part of the conformance requirements. The level of detail required in the prof
25、orma exceeds that of the protocol specification by requiring details to uniquely identify the implementation and the supplier. NOTE - PICS are related to base Recommendations and Standards and only base Recommendations and Standards. PICS structure might be expanded and refined for other documents u
26、sing the base Standards (e.g. EPICS). 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this text, constitute provisions of this Recommendation I International Standard. At the time of publication, the editions indicated w

The PICS proforma Annex A has been designed to be a self contained section of this Recommendation 1 International Standard, for use in testing
36、 and procurement. 6 Conformance A conforming PICS proforma shall be technically equivalent to the ITU-T I ISOAEC published PICS proforma and shall preserve the numbering and ordering of the items in the ITU-T 1 ISOAEC PICS proforma. A PICS which conforms to this Recommendation I international Standa
37、rd shall: a) b) c) describe an implementation which conforms to ITU-T Rec. X.833 I ISO/IEC 11586-4; be a conforming PICS proforma, which has been completed in accordance with the instruction for completion given in A. 1 and A.3; and include the information necessary to uniquely identi both the suppl
38、ier and the implementation. 2 ITU-T Rec.

39、I Intemational Standard) A.l In order to reduce the size of tables in the PICS proforma, notations have been introduced that have allowed the use of a multi-column layout, where the columns are headed Status, and Support. The definition of each of these follows. A.l.l Status column This column indic
40、ates the level of support required for conformance to IT-T Rec. X.833 I ISOAEC 11586-4. The values are as follows: Notations defined for the proforma M Mandatory support is required. O Optional support is permitted for conformance to ITU-T Rec. X.833 1 ISOAEC 11586-4. If implemented it must conform
41、to the specifications and restrictions contained in IT-T Rec. X.833 I ISO/IEC 1 1586-4. These restrictions may affect the optionality of other items. The item is not applicable. The item is conditional (where n is the number which identifies the condition which is applicable). The definitions for th
42、e conditional statements used in this Annex are written under the tables in which they first appear. The item is optional, but the optionality is qualified (where n is the number which identifies the qualification which is applicable). The definitions for the qualified optional statements used in th
43、is Annex are written under the tables in which they first appear. da cn 0.n A.1.2 Support column The Support column shall be completed by the supplier or implementor to indicate the level of implementation of each feature. The proforma has been designed such that the only entries required in the Sup
44、port column are: Y N - Not applicable. Yes, the feature has been implemented No, the feature has not been implemented A.2 PICS numbers Each line within the PICS proforma which requires implementation detail to be entered is numbered at the left hand edge of the line. This numbering is included as a
45、means of uniquely identiQing all possible implementation details within the PICS profonna. The need for such unique referencing has been identified by the testing bodies. The means of referencing individual responses should be to speci the following sequence: a) b) a solidus character, /; c) d) a re
46、ference to the smallest subclause enclosing the relevant item; the reference number of the row in which the response appears; if, and only if, more than one response occurs in the row identified by the reference number, then each possible entry is implicitly labelled a, b, c, etc., from left to righ
47、t, and this letter is appended to the sequence. 1 Copyright release for PICS proforma Users of this Recommendation 1 International Standard may freely reproduce the PICS proforma in this annex so that it can be used for its intended purpose, and may further publish the completed PICS.

In certain clauses of the PICS proforma further guidance for completion may be necessary. Such guidance
49、shall supplement the guidance given in this clause and shall have a scope restricted to the clause in which it appears. in addition, other specifically identified information shall be provided by the implementor where requested. No changes shall be made to the proforma except the completion as required.
