1. Scope
The goal of the Non-repudiation Service is to generate, collect, maintain, make available and validate evidence concerning a claimed event or action in order to resolve disputes about the occurrence or non occurrence of the event or action. This part of ISO/IEC 13888 specifies mechanisms for the provision of some s pecific, communication related non-repudiation Services using asymmetric techniques.
Non-repudiation mechanisms are specified to establish the following non-repudiation services: -
- non-repudiation of origin,Â
- non-repudiation of delivery,Â
- non-repudiation of submission,
- non-repudiation of transport.
Non-repudiation mechanisms involve the exchange of non- repudiation tokens specific for each non-repudiation Service. Non-repudiation tokens consist of digital signatures and additional data. Non-repudiation tokens shall be stored as non- repudiation information that may be used subsequently in case of disputes.
Depending on the non-repudiation policy in effect for a specific application, and the legal environment within which the application operates, additional information may be required to complete the non-repudiation information, e.g.,
- Â evidence including a trusted time stamp provided by a Time S tamping Authority,
- Â evidence provided by a notary which provides assurance about the action or event performed by one or more entities.
Non-repudiation can only be provided within the context of a clearly defined security policy for a particular application and its legal environment. Non-repudiation policies are described in the multipart Standard of Security Frameworks for open systems - Part 4: Non-repudiation Framework, ISO/IEC 10181-4.
