Editorial

Abstract

This special issue comprises of nine selected papers from the International Symposium on Electronic Commerce Security (ISECS 2009), Nanchang, China, 22-24 May 2009. The conference received 1050 paper submissions from 19 countries and regions, of which 487 were selected for presentation after a rigorous review process. From these 487 research papers, through two rounds of reviewing, the guest editors selected twelve as the best papers on the Computers track of the Conference. The candidates of the Special Issue are all the authors, whose papers have been accepted and presented at the ISECS 2009 and WISA 2009, with the contents not been published elsewhere before.

The ISECS 2009 and WISA 2009 are sponsored by Nanchang HangKong University, China, Peoples' Friendship University of Russia, Nanchang University (China), Jiangxi Normal University (China), Wuhan University (China), National Chung Hsing University (Taiwan), Institute of Software, Chinese Academy of Sciences, Sichuan University (China), and Jiaxing University (China). Technical Co-Sponsors of the conference are IEEE, IEEE Computer Society, and IEEE Computer Society Technical Committee on E-Commerce.

“Dynamic Pricing Strategy of Provider with Different QoS Levels in Web Service”, by Lean Yu, Shouyang Wang, Guowei Hua, Gang Xie, and Jinlong Zhang, proposes a new dynamic pricing model to consider order cancellation ration and different QoS levels for maximizing provider revenue.

“Model of Controlling the Hubs in P2P Networks”, by Yuhua Liu, Chun Yang, Kaihua Xu, Naixue Xiong, proposes a new method to avoid generating the hubs in the networks by controlling the logical topology structure of P2P networks, and this controlling method can enhance the anti- vulnerability of P2P networks and ensure the networks develop continually and healthily.

“Interior Link Delay Reference of Ad Hoc Networks Based on End-to-End Measurement: Linear Analysis Model of Delay”, by Yao Ye, Cai Wandong, proposes a interior link delay reference algorithm of Ad Hoc network on the basis of End-to-End measurement method. And resolved the problem of interior link delay inference through computing the solution space for the non- homogenous linear equations based on linear analysis model of delay.

“Model-based Vulnerability Analysis of IMS Network”, by Dong Wang, Chen Liu, proposes a comprehensive vulnerability analysis model of IMS network, and makes a systematic analysis about the security objectives, assets, weaknesses, threats and other attributes of IMS network by using this model.

“Cryptanalysis of Some Client-to-Client Password-Authenticated Key Exchange Protocols”, by Tianjie Cao, Tao Quan, Bo Zhang, proposes that Kwon and Lee’s protocols and Zhu et al.’s protocol are still vulnerable to server-compromise impersonation attacks and a malicious server can eavesdrop the communication between the two clients.

“Ubiquitous Commerce: Theories, technologies, and applications” by Liyi Zhang, Qihua Liu and Xinjian Li, proposes a suitable framework and organize the u-commerce research under the proposed classification scheme. The current situation outlined by the scheme has been addressed by exploratory and early phase studies.

“A United Access Control Model for Systems in Collaborative Commerce”, by Han Ruo-Fei, Wang Hou-Xiang, Xiao Qian, Jing Xiao-Pei, and Li Hui, proposes the existing access control models and propose a united access control model, adopting some useable ideas into it. The proposed model is aimed to control privileges of internal functions and integrate them into service, establish rules for external invoking.

“SWSCF: A Semantic-based Web Service Composition Framework”, by Jianqiang Hu,Juanzi Li, Zhiyong Zeng, proposes a semantic-based Web services composition framework SWSCF which exhibits flexibility to integrate services in terms of application domain semantics and dynamic business requirements.

“The Social Network Mining of BBS”, by Lixin Zhou, Jichang Ding, Yi Wang, Bowen Cheng, Fei Cao, analyze every useful message during their interaction through BBS to mine what kinds of attitudes they show to others, and also get some personal information using data mining technology, to establish the social network, to find out the key figures who are the more active or important BBS users than others.
