Describes generic facilities for assistance in providing security services in OSI applications. Describes protecting transfer syntax, associated with Presentation Layer support for security services in the Application Layer.

1.1 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 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; 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; a specification and PICS proforma for a security transfer syntax, associated with Presentation Layer support for security services in the Application Layer. 1.2 This Recommendation | International Standard defines the protecting transfer syntax, associated with Presentation Layer support for security services in the Application Layer.
