National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and
15、 IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC
16、 JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 11586-1 was prepared by Joint
17、Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 21, Open systems interconnection, data management and open distributed processing, in collaboration with ITU-T.

21、s protocols which support the provision of security services. The parts are as follows: Part 1: Overview, Models and Notation; Part 2: Security Exchange Service Element Service Definition; Part 3: Security Exchange Service Element Protocol Specification; Part 4: Protecting Transfer Syntax Specificat
22、ion; Part 5: Security Exchange Service Element PICS Proforma; Part 6: Protecting Transfer Syntax PICS Proforma. This Recommendation|International Standard constitutes Part 1 of this series. For informative guidelines on the application of all facilities described in this series, see Annex G. It is i
23、mportant to note that these generic security facilities do not in themselves provide security services; they are simply construction tools for security-related protocols. Furthermore, these facilities do not necessarily provide a stand-alone solution to all security communications requirements of ap
24、plications. Application standards may still need to incorporate security features within their specifications, to work in conjunction with generic security services supported by the Generic Upper Layers Security facilities. 1 Scope 1.1 This series of Recommendations|International Standards defines a
25、 set of generic facilities to assist in the provision of security services in OSI applications. These include: a) a set of notational tools to support the specification of selective field protection requirements in an abstract syntax specification, and to support the specification of security exchan
26、ges and security transformations; b) a service definition, protocol specification and PICS proforma for an application-service-element (ASE) to support the provision of security services within the Application Layer of OSI; c) a specification and PICS proforma for a security transfer syntax, associa
27、ted with Presentation Layer support for security services in the Application Layer. 1.2 This Recommendation|International Standard defines the following: a) general models of security exchange protocol functions and security transformations, based on the concepts described in the OSI Upper Layers Se
28、curity Model (ITU-T Rec. X.803|ISO/IEC10745); b) a set of notational tools to support the specification of selective field protection requirements in an abstract syntax specification, and to support the specification of security exchanges and security transformations; c) a set of informative guideli
29、nes as to the application of the generic upper layers security facilities covered by this series of Recommendations|International Standards. 1.3 This Recommendation|International Standard does not define the following: a) a complete set of upper layer security facilities which may be required by oth
30、er Recommendations|International Standards; b) a complete set of security facilities for specific applications; c) the mechanisms employed to support security services. 1.4 The security exchange model, and supporting notation, are intended both for use as the basis of defining the security exchange
31、service element in subsequent parts of this series of Recommendations|International Standards, and for use by any other ASE which may import security exchanges into its own specification.BSISO/IEC11586-1:1996 2 BSI 11-1998 2 Normative references The following Recommendations and International Standa
