Today’s cryptanalysis on symmetric key cryptography is encouraging the use of larger key sizes and complex algorithms to achieve an unbreakable state. However, this leads an increase in computational complexity. This has promoted many researchers to develop high-performance symmetric key cryptography schemes using approaches such as the use of high-end computing hardware. Peer-to-peer (P2P) or ...

Though the phenomenon of ’six degrees of separation’ always attracts many scientists’ attention, yet we haven’t thoroughly understood why our social network has such highly efficient decentralized search ability. Inspired by Kleinberg’s model and the fact that human travel behavior obeying power law distribution in the sense of geographical distance, we constructed a new social network model an...

Data caching strategy for ad hoc networks whose nodes exchange information items in a peer-to-peer fashion. Data caching is a fully distributed scheme where each node, upon receiving requested information, determines the cache drop time of the information or which content to replace to make room for the newly arrived information. These decisions are made depending on the perceived presence of t...

The Internet has evolved from an infrastructure supporting mainly e-mail and web applications, to a generic platform for a broad range of services, including Internet telephony (VoIP), Internet television (IPTV), Peer-to-Peer (P2P) file sharing, and many more. The proliferation of wireless and optical fiber technology has lead to an increase both in terms of network coverage and capacity, which...

While the current Internet architecture is designed based on the host-to-host communication paradigm, the real Internet usage shows that content-oriented traffic is dominant. Good examples of this paradigm shifting are Content Delivery Networks (CDNs) and Peer-to-Peer (P2P) Networks. A CDN is a system of cooperating networked computers and it provides content delivery services to end users tran...

Most of the authors look at peer review as something which is a ‘black box’ and ‘a hurdle to be crossed’. That is ironical as peer review exists to ensure that good science prospers and is shared. A better appreciation of the respective roles of the authors, reviewers and editors is desirable for a good publication to emerge. Over the years, peer review has taken many shapes and continues to ev...

Currently peer review is thought to be slow, expensive, profligate of academic time, highly subjective, prone to bias, easily abused, poor at detecting gross defects, and almost useless for detecting fraud. One cannot predict the future but at present there do not seem to be serious alternatives to peer review. Peer review has been structurally static since the nineteenth century mainly through...
