ABSTRACT

Peer-to-peer systems have the ability to connect network nodes in a convenient and simple manner. Thus, they are used in a broad range of applications to connect nodes with different capabilities in terms of computational power, memory and energy. For all these peer-to-peer systems there doesn't exist a coherent and dynamic security concept which allows application designers to simply specify their security requirements and are thereafter offered security features to protect applications against threats. In this paper we outline a general peer-to-peer model offering a dynamic security concept which allows for simple selection of an appropriate security level.
