Annotation

This series of Recommendations I 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.

This Recommendation I International Standard defines the following:

a) general models of security exchange protocol functions and security transformations, based on the concepts described in the OS1 Upper Layers Security Model (ITU-T Rec. X.803 I ISO/IEC 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 I International Standards.

This Recommendation | International Standard does not define the following:
