8、e International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committ
9、ee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechn

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted

BS ISO 21324:2016CCSDS RECOMMENDED STANDARD FOR SPACE DATA LINK SECURITY CCSDS 355.0-B-1 Page ii September 2015 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of its members. The
16、 Committee meets periodically to address data systems problems that are common to all participants, and to formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommended Standards and are
17、not considered binding on any Agency. This Recommended Standard is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever a member establishes a CCSDS-related st
18、andard, this standard will be inaccord with the relevant Recommended Standard. Establishing such a standarddoes not preclude other provisions which a member may develop.o Whenever a member establishes a CCSDS-related standard, that member willprovide other CCSDS members with the following informatio
19、n:- The standard itself. - The anticipated date of initial operational capability. - The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neitherthis Recommended Standard nor any ensuing standard is a substitute for amemorandum of
20、 agreement.No later than five years from its date of issuance, this Recommended Standard will be reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or newdirections; or (3) be retired
21、or canceled.In those instances when a new version of a Recommended Standard is issued, existing CCSDS-related member standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such standards or implementations are to
22、be modified. Each member is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommended Standard.

23、55.0-B-1 Page iii September 2015 FOREWORD This document describes a protocol for applying security services to the CCSDS Space Data Link Protocols used by space missions over a space link. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent r
24、ights. CCSDS has processes for identifying patent issues and for securing from the patent holder agreement that all licensing policies are reasonable and non-discriminatory. However, CCSDS does not have a patent law staff, and CCSDS shall not be held responsible for identifying any or all such paten
25、t rights. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control procedures, which are defined in Organization and Processes for the C
26、onsultative Committee for Space Data Systems (CCSDS A02.1-Y-4). Current versions of CCSDS documents are maintained at the CCSDS Web site: http:/www.ccsds.org/ Questions relating to the contents or status of this document should be sent to the CCSDS Secretariat at the e-mail address indicated on page

It does not specify: a) individual implementations or products; b) the implementation of service interfaces within real systems; c) the methods or technol
34、ogies 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 4 provides a listing of algorithms recommended b
35、y 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. 1.3 APPLICABILITY This Recommended Standard applies to the creation of Agency standards an
36、d for secure data communications over space links between CCSDS Agencies in cross-support situations. The Recommended Standard includes comprehensive specification of the service for inter-Agency cross support. It is neither a specification of, nor a design for, real systems that may be implemented
37、for existing or future missions. The Recommended Standard specified in this document is to be invoked through the normal standards programs of each CCSDS Agency, and is applicable to those missions for which interoperability and cross support based on capabilities described in this Recommended Stand
38、ard is anticipated. Where mandatory capabilities are clearly indicated in sections of the ISO 21324:2016(E) ISO 2016 All rights reservedBS ISO 21324:2016CCSDS RECOMMENDED STANDARD FOR SPACE DATA LINK SECURITY CCSDS 355.0-B-1 Page 1-2 September 2015 Recommended Standard, they must be implemented when
39、 this document is used as a basis for interoperability and cross support. Where options are allowed or implied, implementation of these options is subject to specific bilateral cross support agreements between the Agencies involved. 1.4 RATIONALE The goals of this Recommended Standard are to: a) pro
40、vide a standard method of applying security at the Data Link Layer, independent of the underlying cryptographic algorithms employed by any particular space mission; b) preserve compatibility with existing CCSDS Space Data Link Protocol Transfer Frame Header and Trailer formats and frame processing i
41、mplementations so that, where appropriate, legacy frame processing infrastructure may continue to be used without modification; c) preserve compatibility with the CCSDS Space Link Extension (SLE) forward and return services; and d) facilitate the development of common commercial implementations to i
42、mprove interoperability across agencies. More discussion of the Security Protocols goals and design choices, including its interaction with other CCSDS services, may be found in reference D3. 1.5 DOCUMENT STRUCTURE This document is organized as follows: Section 1 presents the purpose, scope, applica
43、bility, and rationale of this Recommended Standard and lists the conventions, definitions, and references used throughout the document. Section 2 (informative) provides an overview of the Security Protocol. Section 3 (normative) defines the services provided by the protocol entity. Section 4 (normat
44、ive) specifies the protocol data units provided for these services and the procedures employed by the service provider. Section 5 (normative) specifies the constraints associated with these services for each of the supported Space Data Link Protocols. Section 6 (normative) lists the managed paramete
45、rs associated with these services.
