Summary:
|
Non-repudiation is to prevent entities from denying that they have sent or received electronic transaction data in the telecommunication network. This Recommendation will create an enhanced non-repudiation model based on Recommendation ITU-T X.813 in support of application services. The architecture can generate and verify the non-repudiation evidence for the transaction data by trusted third party (TTP) that is the central sign authority (CSA).
The architecture integrates multiple authentication devices to access the trusted third party that is the central signing authority (CSA). It also integrates multiple service providers to provide a non-repudiation service with a single authenticated device. The delegated non-repudiation architecture manages user authentication centrally. The service providers can provide the service of a user authentication and non-repudiation without additional construction of authentication systems.
This Recommendation describes the delegated non-repudiation service models and operations for each of the service models. This architecture also defines the security requirements of the delegated non-repudiation service.
The delegated non-repudiation architecture reduced the computation and operations of client aspects for user authentication and non-repudiation service. Thus this delegated non-repudiation architecture is more suitable for mobile devices.
