Modeling adaptive non-repudiation security services

Abstract

Non-repudiation security service helps to protect an electronic system against false denial of performing certain actions by the participants of communication involving that system. In the development process of such a security service it is important to implement all the necessary elements and adapt them in accordance with the defined protection scope. There are several types of non-repudiation and cases of their use. In this paper the author focuses on the situation when a nonrepudiation service is being implemented on an application server. All necessary actions of the users i.e. of people and/or machines are recorded by the service. Currently a new type of security services called “context-aware security services” is under studies. This type of service involves acquiring and processing additional information in order to provide flexible protection. This paper presents the elements of non-repudiation security service and how the elements can be modeled with context awareness support including reputation systems.
