The traditional distributed individual rekeying protocols are inefficient and have high rekeying cost, while batch rekeying protocols are vulnerable to collusions attack. Aiming at those drawbacks, three algorithms are presented: 1) MST algorithm, which is used to merge two subtrees; 2) CARR algorithm, which is resistant to collusions attack, and can avoid a renewed node to be rekeyed more than once;...
Recently there have been increasing attentions on the security aspects in Peer-to-Peer (P2P) networks, especially with respect to worm epidemics. However, existing worm containment mechanisms can be largely ineffective due to the long delay exhibited in worm identification and patch generation. In this paper, we propose a new worm containment algorithm based on the concept of overlay partition, which...
Online storage systems that provide versatile and convenient platforms for content distribution have attracted significant attention over the Internet. To guarantee adequate levels of service quality and to minimize server cost, such systems typically deploy dedicated servers while effectively utilizing peer bandwidth in a complementary fashion. It is essential to understand the role of servers and...
Peer-to-peer (P2P) live video streaming systems have recently received significant attention, with commercial deployment gaining increased popularity in the Internet. It is evident from our experiences with real-world systems that, it is not uncommon to have hundreds of thousands of users trying to join a program in the first few minutes of a live broadcast. This phenomenon, unique in live streaming...
It has been widely acknowledged that online storage systems within the "cloud" of the Internet provide services of a substantial value to end users who wish to share files of any sizes within a group. Such online storage services are typically provided by dedicated servers, either in content distribution networks (CDNs) or large data centers. Server bandwidth costs, however, are prohibitive...
