JXTA-Overlay: A P2P Platform for Distributed, Collaborative, and Ubiquitous Computing

Abstract

With the fast growth of Internet infrastructure and the use of large-scale complex applications from industries, transport, logistics, government, health and businesses, there is an increasing need to design and deploy multi-featured networking applications. Important features of such applications include the capability to be self-organized, decentralized, integrate different types of resources (PCs, laptops, mobile and sensor devices), and provide global, transparent and secure access to resources. Moreover, such applications should support not only traditional forms of reliable distributing computing and optimization of resources but also various forms of collaborative activities such as business, online learning and social networks in an intelligent and secure environment. In this paper, we present the JXTA-Overlay, a JXTA-based P2P platform designed with the aim to leverage capabilities of Java, JXTA and P2P technologies to support distributed and collaborative systems. The platform can be used not only for efficient and reliable distributed computing but also for collaborative activities and ubiquitous computing by integrating in the platform end-devices. The design of an user interface as well as security issues are also tackled. We evaluate the proposed system by experimental study and show its usefulness for massive processing computations and e-learning applications.

Breaking a Robust Remote User Authentication Scheme Using Smart Cards

“…S first checks the validity of h(ID i ) and T u , computes EID=ID i || m and 2 C ′ =h(h(EID ⊕ x) ⊕ T u ), and then compares the computed 2 C ′ with the received C 2 . If they are equal, S computes C 3 =h(h(EID ⊕ x) ⊕ h(T s )) and session key…”

“…With the development of distributed computer networks, it is easy for user terminals to share information and computing power with hosts [1,2]. The distributed locations of service providers make it efficient and convenient for subscribers to access the resources, and it is of great concern to protect the systems and the users' privacy and security from malicious adversaries.…”

Study of Network Size Measurement Algorithm for P2P System

“…Object placement is also determined by globally-agreed schemes highly related to overlay networks. Among these systems Distributed Hash Tables (DHTs) have emerged as the most popular scheme in this family [2,3]. CAN implements a distributed hash table, which provides basic operations such as insertion, lookup, and deletion of some objects [4].…”

Survey on Approaches to Secure Sso Mechanism

“…With wide spreading of distributed computer networks, it has become popular to allow users accessing various network services offered by distributed service providers [1], [2]. Consequently, user authentication (also called user identification) [3], [4] plays a crucial role in distributed computer networks to verify if a user is legal and then can be granted to access the services requested.…”
