Draft documents are subject to change, and the draft CCSDS Recommendation referenced here does not necessarily represent consensus technical agreement among the CCSDS Member Agencies.

The Management Council of the Consultative Committee for Space Data Systems (CCSDS) has authorized the publication, and requests Agency review, of the following document:

This Recommended Standard specifies a security protocol for CCSDS data links. The 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 to provide a structured method for applying data authentication and/or data confidentiality at the Data Link layer. The current draft update adds specifications for Unified Space Data Link Protocol support and adds normative reference to Space Data Link Security Protocol—Extended Procedures.
