4、 was prepared by ITU-T Study Group 8 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 1st of April 1999. i Recommendation T.36/Amd.l (04/99) . FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- catio
5、ns. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommun
6、ication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups 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
7、 Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and EC. NOTE In this Recommendation the term recognized operating agency (ROA) includes any individual, company, corporation or governme
8、ntal organization that operates a public correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Reco
9、mmendation 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 development process. As of the date o
10、f approval of this Recommendation, the ITLJ 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 therefore strongly urged to consu

13、NT 1 (Geneva, 1999) 1) Subclause A.2.2 Amend A.2.2 to read as follows: A.2.2 Functions Key management is provided using the HKM system defined in Annex CR.36. Three procedures are defined: 1) 2) 3) the registration mode (see C.4); the secure mode (see C.5); and the override mode (see C.7). Registrat
14、ion establishes mutual secrets and enables all subsequent transmissions to be provided securely. In subsequent transmissions, the HKM system provides mutual authentication, a secret session key for document confidentiality and integrity, confirmation of receipt and a confirmation or denial of docume
15、nt integrity. Document confidentiality is provided using the carrier cipher defined in Annex DiT.36. The carrier cipher uses a 12-decimal digit key which is approximately equivalent to 40 bits. Document integrity is provided using the system defined in Annex EK.36. This annex defines the hashing alg
16、orithm including the associated calculations and information exchange. 2) New subclause C.7 Add a new subclause C. 7 to read as follows: C.7 Override mode The override mode allows the terminal operators to communicate independently and in secret using two secure facsimile terminals conforming to Rec
17、ommendation T.36 without carrying out a registration process between the two terminals. This is accomplished by by-passing the automatic key management procedures of the secure mode (see C.5). No mutual primitive is generated, no registered crypt number is retrieved and no secret session key is esta
18、blished. Instead, a mutually agreed pre-arranged 12-digit secret session key is entered by the terminal user at the sending terminal which is used with a carrier cipher to provide document confidentially. The terminal user at the receiving terminal enters the same mutually agreed key which is used w
19、ith the carrier cipher to decrypt the received document.
