Foreword

GB/T 17903 under "Information technology - Security techniques - Non - repudiation" general title, consists of the following components. --- Part 1. General; --- Part 2. Mechanisms using symmetric techniques; --- Part 3. Mechanisms using asymmetric techniques. This part of GB/T 17903 Part 2, identical with ISO /IEC 13888-2.1998 "Information technology - Security techniques - against Lai - Part 2. Symmetric technology mechanism ", only editorial changes. ISO /IEC 13888-2.1998 by the Joint Technical Committee ISO /IEC JTC1 (IT) technical committee SC27 (IT security technology) raised. This Part replaces GB/T 17903.2-1999 "Information technology - Security techniques - Non - repudiation - Part 2. Machine symmetric techniques system". This section compared with the GB/T 17903.2-1999, the main differences are as follows. --- This part under the revised Part 1, change some of the terms. --- This section describes part of the text has been revised and amended Chapter 10 of "NORT".

1 Scope

Non-repudiation service is designed to generate, collect, maintain, use and verification of evidence has claimed about events or actions to address about the event or Action or dispute occurred has occurred. This section describes the general structure for non-repudiation services, as well as some specific and relevant communication The mechanism for providing primary non-repudiation (NRO), the delivery of non-repudiation (NRD), to submit non-repudiation (NRS) and transport non-repudiation (NRT) and the like. Other non-repudiation services are available in Chapter 8 describes the general structure constructed to meet the requirements of security policy. This section relies on a trusted third party to prevent fraudulent repudiation. Generally it requires an online trusted third party. Non-repudiation Non-repudiation protocol provides mechanisms for the exchange of a variety of non-repudiation services provided token. Used in this section of the anti-repudiation token By the security envelope and additional data. Non-repudiation Non-repudiation token as information to be stored, used to prepare after a dispute arises. Repudiation of the strategy and operations in which the application is based on the particular application of an effective anti-legal environment, non-repudiation may include the following additional information information. a) include a trusted time stamp time stamp agencies, including the evidence; Evidence b) notaries will be available to ensure that actions or events are executed by one or more entities or participation. Non-repudiation before the entry into force only in a particular application and its legal environment, there is a clearly defined security policy scope.
