Modeling Adaptive Non-Repudiation Security Services

Non-repudiation security service helps to protect electronic systems against false denial of performing certain actions by the participants of the communication, involving that system. While developing such security service it is important to implement all the necessary elements and adapt them according to defined protection scope. There are several types of non-repudiation and its use cases. This paper focuses on the case where non-repudiation service is implemented on the application server and records all the necessary actions of users which are people as well as machines. Currently there is new type of security services under studies, named context aware security services. It involves additional information in order to provide flexible protection. This paper presents non-repudiation security service elements and how they can be modeled with context awareness support including reputation systems.
