8、TY TRANSFORMATIONS APPLICATION SERVICE ELEMENT FOR REMOTE OPERATIONS SERVICE ELEMENT (STASE-ROSE) Summary This Recommendation provides specifications to support security transformations, such as encryption, hashing, sealing and signing, focusing on whole Remote Operations Service Element (ROSE) Prot

9、ocol Data Units (PDUs). Security transformations are used to provide various security services such as authentication, confidentiality, integrity and non-repudiation. This Recommendation describes an approach to the provisioning of security transformations that is implemented in the application laye

10、r and requires no security-specific functionality in any of the underlying OS1 stack layers. Source ITU-T Recommendation 4.813 was prepared by ITU-T Study Group 4 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 26th of June 1998.

11、RECMN Q-833-ENGL 1998 4862593 Ob55385 T93 m FOREWORD IT (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying

12、 technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups

13、 which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared o

14、n a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the pract

15、ice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation dev

16、elopment process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are

17、therefore strongly urged to consult the TSB patent database. O ITU 1999 All rights reserved.

27、APPLICATION SERVICE ELEMENT FOR REMOTE OPERATIONS SERVICE ELEMENT (STASE-ROSE) (Geneva, 1998) 1 Scope, Purpose and Application 1.1 Scope Security Transformations (ST) are used to provide various security services such as peer entity authentication, data origin authentication, confidentiality, integr

28、ity and non-repudiation. Security transformations include encryption, hashing, digital seals and digital signatures. This Recommendation supports security services for ROSE PDUs within the application layer. It is independent of the underlying communications protocol stack. This Recommendation defin

29、es a new Application Service Element (ASE) called Security Transformations Application Service Element for ROSE (STASE-ROSE), which resides between the ROSE and the Presentation Layer in the OS1 Protocol Stack. This Recommendation provides an approach for performing Security Transformations (ST) tha

30、t imposes no requirements on any of the 6-lower layers of the communications stack. This is in contrast to methods e.g. Generic Upper Layers Security (GULS) that support security transformations through embedded functionality in the communications stack at the presentation layer. This Recommendation

31、 further provides for peer entity authentication at association Set-up time; for the negotiation of security parameters (such as security algorithms) that will be used in the course of the association; and for dynamic update, in the course of the association, of security parameters that are used for

32、 individual protocol data units. The method presented in this Recommendation could be adapted for ASES other than ROSE that interact directly with the presentation layer. However, this Recommendation focuses on ROSE and does not cover any possible extensions or generalizations. How the actual securi

33、ty transformations are performed (e.g. producing and verifiing digital signatures) is a local matter outside the scope of this Recommendation. In particular, the use of a generic security module, such as the Generic Security Service - Application Programming Interface (GSS-API) for performing securi

34、ty transfomations is a local matter. Nevertheless, while this Recommendation does not mandate the use of GSS-API, it provides the necessary framework for using GSS-API together with STASE-ROSE (see Appendix III). Key management is an important component of a security infrastructure. This Recommendat

35、ion supports the exchange of information related to cryptographic keys. However, a general framework for key management is outside the scope of this Recommendation. Recommendation Q.813 (06/98) 1 1.2 Purpose The purpose of this Recommendation is to protect whole ROSE PDUs. Recommendation Q.8 12 spec

36、ifies File Transfer Administration and Management (FTAM), Common Information Management Application Service Element (CMISE) and X.500 Directory in the application layer for the Q3 and X interfaces of the Telecommunications Management Network (TMN). X.500 and CMISE use the services of the Remote Oper

37、ation Service Element (ROSE). This Recommendation addresses the security of ROSE Protocol Data Units (PDUs). While this Recommendation is motivated by the need to secure TMN interactions or message exchanges, it can be used to provide security for any application that uses ROSE. 1.3 Application This

38、 Recommendation applies to ROSE-based applications such as user applications that use CMISE or X.500 Directory. Providing protection for CMIP PDUs is a major goal of this Recommendation. Since CMIP is based on the 1988 version of ROSE (see Recommendations X.219 and X.229), this Recommendation also f

39、ocuses on that version, rather than the 1994 version (see Recommendations X.880, X.881 and X.882). Therefore this Recommendation may not apply to the current version of Recommendation X.500 which is based on the 1994 version of ROSE. 2 References The following ITU-T Recommendations and other referen
