27、sion) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO

28、and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/

29、IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national

30、 bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. In exceptional circumstances, the joint technical committee may propose the publication of a Technical Report of one of the following types: type 1, when the require

31、d support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an International Standard; type 3,

32、 when the joint technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example). Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be t

33、ransformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of paten

34、t rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC TR 14516, which is a Technical Report of type 3, was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 27, IT Security techniques, in collaboration wi

35、th ITU-T. The identical text is published as ITU-T Rec. X.842. ISO/IEC TR 14516:2002(E) vi ISO/IEC 2002 All rights reservedIntroduction Achievement of adequate levels of business confidence in the operation of IT systems is underpinned by the provision of practical and appropriate legal and technica

36、l controls. Business must have confidence that IT systems will offer positive advantages and that such systems can be relied upon to sustain business obligations and create business opportunities. An exchange of information between two entities implies an element of trust, e.g. with the recipient as

37、suming that the identity of the sender is in fact the sender, and in turn, the sender assuming that the identity of the recipient is in fact the recipient for whom the information is intended. This “implied element of trust“ may not be enough and may require the use of a Trusted Third Party (TTP) to

38、 facilitate the trusted exchange of information. The role of TTPs includes providing assurance that business and other trustworthy (e.g. governmental activities) messages and transactions are being transferred to the intended recipient, at the correct location, that messages are received in a timely

39、 and accurate manner, and that for any business dispute that may arise, there exist appropriate methods for the creation and delivery of the required evidence for proof of what happened. Services provided by TTPs may include those necessary for key management, certificate management, identification

40、and authentication support, privilege attribute service, non-repudiation, time stamping services, electronic public notary services, and directory services. TTPs may provide some or all of these services. A TTP has to be designed, implemented and operated to provide assurance in the security service

41、s it provides, and to satisfy applicable legal and regulatory requirements. The types and levels of protection adopted or required will vary according to the type of service provided and the context within which the business application is operating. The objectives of this Recommendation | Technical

42、 Report are to provide: a) Guidelines to TTP managers, developers and operations personnel and to assist them in the use and management of TTPs; and b) Guidance to entities regarding the services performed by TTPs, and the respective roles and responsibilities of TTPs and entities using their servic

43、es. Additional aspects covered by this Recommendation | Technical Report are to provide: a) An overview of the description of services provided; b) An understanding of the role of TTPs and their functional features; c) To provide a basis for the mutual recognition of services provided by different T

44、TPs; and d) Guidance of interworking between entities and TTPs. ISO/IEC TR 14516:2002 (E) ITU-T Rec. X.842 (10/2000) (E) 1 TECHNICAL REPORT ISO/IEC TR 14516 ITU-T RECOMMENDATION X.842 INFORMATION TECHNOLOGY SECURITY TECHNIQUES GUIDELINES FOR THE USE AND MANAGEMENT OF TRUSTED THIRD PARTY SERVICES 1 S

45、cope Associated with the provision and operation of a Trusted Third Party (TTP) are a number of security-related issues for which general guidance is necessary to assist business entities, developers and providers of systems and services, etc. This includes guidance on issues regarding the roles, po

46、sitions and relationships of TTPs and the entities using TTP services, the generic security requirements, who should provide what type of security, what the possible security solutions are, and the operational use and management of TTP service security. This Recommendation | Technical Report provide

47、s guidance for the use and management of TTPs, a clear definition of the basic duties and services provided, their description and their purpose, and the roles and liabilities of TTPs and entities using their services. It is intended primarily for system managers, developers, TTP operators and enter

48、prise users to select those TTP services needed for particular requirements, their subsequent management, use and operational deployment, and the establishment of a Security Policy within a TTP. It is not intended to be used as a basis for a formal assessment of a TTP or a comparison of TTPs. This R

49、ecommendation | Technical Report identifies different major categories of TTP services including: time stamping, non-repudiation, key management, certificate management, and electronic notary public. Each of these major categories consists of several services which logically belong together. 2 References 2.1 Identical Recommendations | International Standards IT U-T Recommendation X.509 (2001) | ISO/IEC 9594-8:2001, Inform
