HOW TO SUBSCRIBE
This Recommended Standard defines the Security Protocol in terms of:
a) the protocol data units employed by the service provider; and
b) the procedures performed by the service provider.
It does not specify:
a) individual implementations or products;
b) the implementation of service interfaces within real systems;
c) the methods or technologies required to perform the procedures; or
d) the management activities required to configure and control the service.
This Recommended Standard does not mandate the use of any particular cryptographic algorithm with the Security Protocol. Reference  provides a listing of algorithms recommended by CCSDS; any organization should conduct a risk assessment before choosing to substitute other algorithms. Annex E (non-normative) defines baseline implementations suitable for a large range of space missions.
The purpose of this Recommended Standard 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 -) to provide a structured method for applying data authentication and/or data confidentiality at the Data Link Layer.
