Providing confidentiality, integrity, and availability is indispensable for secure systems. In particular, almost every commerce application requires that integrity be provided in a secure manner, such that the integrity of data is retained even if the owner of the data is malicious. However, providing secure integrity in mobile environments, where participating nodes and their communication channels...
This paper presents an architectural model for wireless peer-to-peer (WP2P) file sharing system for ubiquitous mobile devices. File sharing is one of the rationales for computer networks with increasing demand for file sharing applications and technologies in small and large enterprise networks and on the Internet. With the popularity of mobile phones in day-to-day activities, P2P file sharing in...
The trend on the proliferation of handheld devices triggered an increase on the development of pervasive and personalized mobile applications that exploit and support peer-to-peer/ad-hoc networks. This creates the conditions and motivation for a mobile electronic ID system, preferably one which provides a friendly privacy solution. The existing mobile identification solutions place the interviewer...
In open environments, such as mobile peer-to-peer systems, participants may need to access resources from unknown users. A critical security concern in such systems is the access of faulty resources, thereby wasting the requester's time and energy and possibly causing damage to her system. A common approach to mitigating the problem involves reputation mechanisms; however, since reputation relies...
The development of dependable mobile P2P systems is an inherently challenging task since such systems may operate in largely uncontrolled environments and may engage new peers or lose existing ones without any form of centralised control. In these circumstances, dependability and security can be enhanced through the runtime monitoring (a.k.a. dynamic verification) of the compliance of the system behaviour...
