It is the UK implementation of, and i
8、s identical to, ISO 8731-1:1987 “Banking Approved algorithms for message authentication Part 1: DEA”, published by the International Organization for Standardization (ISO), except that the title of the British Standard differs in order to more accurately reflect the actual contents of the text. The
9、following list includes all parts of the International Standard. Part 1: DEA; Part 2: Message Authenticator Algorithm. This Part of BS 7102 implements the international text without change for the reasons given below (see “Reasons for implementation”), even though particular attention is drawn (see
10、“Special attention”) to some features that may need special consideration when this standard is being used. The UK actively participated in the development of the International Standard through BSI Technical Committee IST/12 and fully approved publication of the International Standard. The informati
11、on provided in this Part of BS 7102 is considered sufficient to act in the UK as a basis for the use of DEA for banking message authentication. There are no plans at present to supplement this British Standard with any additional guidance, and any comments or enquiries on the International Standard
12、or its application should be addressed to the Secretary to IST/12 at the BSI headquarters address. Reasons for implementation. This Part of BS 7102 implements the International Standard for the following reasons. a) Because information technology equipment, services and systems tend to be, and gener
13、ally need to be, designed, purchased and used in a world-wide context IST/- policy is to agree, wherever possible, standards at international level and not to prepare unique national standards. At the time of its approval, the text of the International Standard was considered to be the best that cou
14、ld be achieved, taking into account both the needs of the “market place” and the “state of the art” in this subject area, and the International Standardization process. b) Further development of the international text at international level has been accorded relatively low priority in relation to ot
15、her projects in the same international committee. c) Publication of British Standards corresponding to the International Standards in which IST/- resources were invested will ensure that the BSI Catalogue becomes, and then remains, a comprehensive first source of information for UK users of IT equip
16、ment and services about the availability of International Standards on IT subjects. In turn, this will facilitate UK use of, and access to, those standards. Special attention. Special attention is drawn to the following feature of the International Standard that, ideally, requires further considerat
17、ion at international level, but it is emphasized that this feature does not prevent use of this standard as a set of basic guidelines and, with appropriate care, products or systems can be effectively standardized. Users of this British Standard, however, might need supplementary information on this
18、 feature from the BSI Technical Committee or from experts in the field. a) The use of DEA may involve the application of items subject to patents in the UK and elsewhere. Intending users are advised to make any necessary checks. Reference should be made, in particular, to the amended version of ISO
19、8372:1987 (in preparation). Licensed Copy: London South Bank University, London South Bank University, Fri Dec 08 09:58:49 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 7102-1:1989 BSI 11-1999iii The BSI Technical Committee has reviewed the provisions of ANSI X3.92:19811), ANSI X3.106:19831) and ANS
20、I X9.9:19822), to which references are made in the International Standard, and has decided that they are acceptable for use in conjunction with this British Standard. Information on the availability of interim ISO documents, as well as up-to-date information on existing and projected British Standar
21、ds publications in the general area of Information Technology, is included in the “BASIC LIST” and regular Newsletter published as part of the BSI Information Technology Services (BITS) initiative. A British Standard does not purport to include all the necessary provisions of a contract. Users of Br
22、itish Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, pages 1 and 2, an inside back cover and a back co
23、ver. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.
