Scope

Non-repudiation service aims to generate, collect, maintain, make available and confirm evidence of declared events or actions, so as to resolve disputes about the occurrence or non-occurrence of certain events or actions. This standard describes the general structure that can be used for non-repudiation services, as well as specific communication mechanism. Other non-repudiation services can be composed using the general structure described in clause 8 to meet the requirements of the security policy. This International Standard uses trusted third parties to prevent repudiation. An online trusted third party is generally required. The non-repudiation mechanism provides a protocol for exchanging non-repudiation tokens specific to each non-repudiation service. A non-repudiation token consists of a secure envelope and additional data. Non-repudiation tokens should be stored as non-repudiation information and used in future disputes. According to the non-repudiation strategy used in a particular application and the legal environment in which the application is located, the non-repudiation information may include the following additional information: a) Including evidence of a credible time stamp generated by the time stamping authority; b) The notary provides evidence that provides assurance about actions or events performed by one or more entities. The term non-repudiation can only be effective in a security policy clearly defined by a specific application and its legal environment.
