The purpose of ISO 21324:2016 is to specify the Space Data Link Security Protocol (hereafter referred as the Security Protocol) for CCSDS data links. This protocol provides a security header and trailer along with associated procedures that may be used with the CCSDS Telemetry, Telecommand, and Advanced Orbiting Systems Space Data Link Protocols (references [1]-[3]) to provide a structured method for applying data authentication and/or data confidentiality at the Data Link Layer.

Overview

ISO 21324:2016 - "Space data and information transfer systems - Space data link security protocol" specifies the Space Data Link Security Protocol for CCSDS data links. Adopted from CCSDS 355.0-B-1 (first edition 2016‑11‑15), the standard defines a structured method for applying data authentication and/or data confidentiality at the Data Link Layer by introducing a security header and security trailer plus associated procedures. It is designed to work with CCSDS Telemetry (TM), Telecommand (TC), and Advanced Orbiting Systems (AOS) Space Data Link Protocols to enable interoperable, cross‑Agency secure links for space missions.

Key topics and requirements

Scope and purpose: Defines protocol data units and service procedures for Data Link Layer security; does not mandate specific implementations or interface designs.

Security primitives: Provides structure for applying data authentication and confidentiality via header/trailer constructs integrated into space link frames.

Protocol services: Specifies sending/receiving behavior, security association management, and service functions applicable to TM, TC and AOS.

Baseline implementations: Annex E describes non‑normative baseline modes suitable for many missions; the standard itself does not require particular cryptographic algorithms.

Conformance & management: Includes managed parameters, conformance requirements and a Protocol Implementation Conformance Statement (PICS) proforma.

Interoperability focus: Intended for cross‑support among CCSDS member agencies; mandatory capabilities must be implemented for interoperability.

Practical applications

ISO 21324:2016 is used when secure space link communications are required between spacecraft and ground systems or between agencies. Typical use cases include:

Protecting telemetry and telecommand links from spoofing or unauthorized access.

Enabling interoperable, cross‑Agency secure operations in multi‑agency missions and ground station networks.

Defining security behavior for mission planners, system integrators and flight software teams without prescribing specific cryptographic implementations.

Who uses it:

Space agencies and program offices (for cross‑support and standards alignment)

Satellite and payload system architects and integrators

Ground segment and network operators (ground stations, TT&C centers)

Security engineers and mission assurance teams
