Full title and description

St ISO IEC 11586-4-1996 — Information technology — Open Systems Interconnection — Generic upper layers security: Protecting transfer syntax specification. This part defines a protecting transfer syntax and related generic facilities used to represent, transfer and negotiate protected (transformed) application data and associated parameters for OSI upper‑layer security.

Abstract

Defines a set of generic facilities to assist in the provision of security services in OSI applications and specifies the protecting transfer syntax (the structure and encoding rules for packaging transformed user data and its security parameters). The text is declared identical to ITU‑T Recommendation X.833.

Scope

This part of ISO/IEC 11586 specifies a protecting transfer syntax for use in OSI upper‑layer security: how security transformations' outputs (protected data, static/dynamic parameters and identifiers) are represented, encoded and negotiated between communicating entities. It is intended to interoperably carry transformed application data and to interwork with the Generic Upper Layers Security (GULS) framework; the text is aligned with and identical to ITU‑T Rec. X.833.

Key topics and requirements

• Definition of the protecting transfer syntax structure for packaged transformed data and associated parameters.
• ASN.1 type definitions and encoding rules (initial encoding + security transformation results).
• Mechanisms for indicating transformation identifiers, static and dynamic unprotected parameters, and transformed data fields.
• Negotiation and signaling considerations for using protecting transfer syntaxes in Presentation/OSI contexts.
• Conformance framework references and relationship to PICS proforma (see ISO/IEC 11586‑6) for implementation statements and testing.

Typical use and users

Used by protocol designers, implementers of OSI application-layer security, test laboratories, conformance assessors and procurers who require a standardized representation and transfer mechanism for protected application data. Implementers complete the related PICS proforma when claiming conformance.

FAQ

Q: What is this standard?

A: ISO/IEC 11586‑4:1996 is the part of the Generic Upper Layers Security series that specifies the protecting transfer syntax used to package and convey transformed (protected) application data in OSI environments; it is identical to ITU‑T Rec. X.833.

Q: What does it cover?

A: It covers the data structures, ASN.1 type definitions, encoding/transfer rules and negotiation signaling needed to represent and move protected application data and associated parameters between systems.

Q: Who typically uses it?

A: Protocol architects, implementers of OSI application‑layer security, test houses, conformance labs and organizations procuring interoperable secure OSI applications. Implementers use the related PICS proforma (Part 6) for conformance declarations.

Q: Is it current or superseded?

A: The ISO record shows ISO/IEC 11586‑4:1996 as published and later reviewed/confirmed (stage 90.93); the text remains the published edition and is declared identical to ITU‑T X.833. Users should check national catalogues or ISO/IEC web stores for the latest lifecycle status before procurement.

Q: Is it part of a series?

A: Yes — it is one part of ISO/IEC 11586 (Generic Upper Layers Security). Companion parts include the overview/models (Part 1), other technical parts on security transformations and the PICS proforma (e.g., Part 6) and the corresponding ITU‑T X.83x Recommendations.

Q: What are the key keywords?

A: Protecting transfer syntax; GULS; OSI; ASN.1; security transformation; transfer syntax; ITU‑T X.833.
