適用范圍：1 This series of Recommendations | International Standards defines a 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 exchanges 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, associated with Presentation Layer support for security services in the Application Layer. 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 Security Model (ITU-T Rec. X.803 | ISO/EC 10745); 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 guidelines as to the application of the generic upper layers security facilities covered by this series of Recommendations | International Standards. 3 This Recommendation | International Standard does not define the following: a) a complete set of upper layer security facilities which may be required by other Recommendations | International Standards; b) a complete set of security facilities for specific applications; c) the mechanisms employed to support security services. 4 The security exchange model, and supporting notation, are intended both for use as the basis of defining the security exchange 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.
