Formal Verification of the Merchant Registration Phase of the SET Protocol

引用

International Journal of Automation and computing 2005年第2期2卷 155-162页

作者： Xiao-qi ma Xiao-Chun Cheng Department of Computer Science The University of Reading Reading UK

This paper describes the formal verification of the Merchant Registration phase of the Secure Electronic Transactions (SET) protocol, a realistic electronic transaction security protocol which is used to protect the secrecy of online purchases. A number of concepts, notations, functions, predicates, assumptions and rules are introduced. We describe the knowledge of all legal participants, and a malicious spy, to assess the security of the sub-protocol. Avoiding search in a large state space, the method converges very quickly. We implemented our method in the Isabelle/Isar automated reasoning environment, therefore the whole verification process can be executed mechanically and efficiently. Keywords Formal verification - electronic transaction protocol - knowledge-based system This work was supported by EC, EPSRC, the National Natural Science Foundation of China (No.60496320, 60496321), and Hong Kong K C Wang Education Foundation.Xiao-qi ma graduated from Nanjing University of Science and Technology, China, in 1997. He received his master’s degree from the Institute of Software, Chinese Academy of Sciences in 2003. He is currently a PhD student at the University of Reading. His research interests include computer network security, knowledge-based systems, and operating systems.Xiao-Chun Cheng obtained his PhD in 1996. He has worked as a lecturer at the University of Reading since 2000. He is a guest professor at North East Normal University and Beijing Normal University. His research interests include theoretical and applied aspects in decision support systems, knowledge-based systems and intelligent systems.

Objective To establish a conceptual model of automatic early warning of infectious diseases based on internet reporting surveillance system, with a view to realizing an automated warning system on a dally basis and timely identifying potential outbreaks of infectious diseases. Methods The statistic conceptual model was established using historic surveillance data with movable percentile method. Results Based on the infectious disease surveillance information platform, the conceptual model for early warning was established. The parameter, threshold, and revised sensitivity and specificity of early warning value were changed to realize dynamic alert of infectious diseases on a dally basis. Conclusion The instructive conceptual model of dynamic alert can be used as a validating tool in institutions of infectious disease surveillance in different districts.

清中期的铜铅产地集中于西南一隅,而币材需求遍及全国。产销分离使铜铅运输成为币材供给不可或缺的重要环节,关乎全国的币制稳定和经济发展。本文从清前期的币材危机出发,探讨清中期铜铅运销体系和币材供给格局形成的原因、过程及保障机制。研究认为,清中期西南边疆矿业的兴起是政府应对前期币材危机的结果,伴随滇铜黔铅外销区域的扩展,形成了以云贵为源头、辐射全国、水陆联运的铜铅运销体系,构成了涵盖全国的币材供给格局。这一体系和格局持续长达一个多世纪,反映出清政府币材安全保障和战略资源调控的能力和水平。

清代前期矿业政策在开与禁之间几经调整,但矿产开发的区域性一直存在,滇、黔、川、湘、桂、粤等矿产大省均于矿政开禁之前获准开矿,绝大部分位于边疆地区。这种矿业格局的形成,除了受制于矿产资源分布和采冶技术之外,国家"开边禁内"思想成为矿业开发的政策导向,笔者称之为边疆战略,亦左右着清代的矿业格局,而这种矿业布局对清代矿业发展和边疆社会产生了重要的影响。
