各部門、各單位:

應我校網絡空間安全學院邀請,西安電子科技大學馬文平教授、武漢大學何德彪教授、武漢理工大學夏喆副教授將于112日來我校做專題學術講座,歡迎廣大師生參加!報告的具體安排如下:

報告時間:2019112日(周六)下午14:0018:30

報告地點:網絡空間安全學院會議室。

告一:Data security and privacy protection authentication scheme in TMIS(马文平 教授)112日下午14:00-1530

   要: Telecare Medical Information System (TMIS) network is a typical functional network, which integrates various types of mobile devices and communication technologies to upgrade the traditional face-to-face medical treatment model to intelligent one, which can provide the flexible and convenient e-health care. Real-time and comprehensive information collection, storage, sharing and processing functions for the personalized medical service are provided in TMIS. The privacy and security risks in TMIS are the main obstacles to the wide deployment of (TMIS). Traditional public key cryptography (PKC) systems support confidentiality and integrity for data storage. However, traditional PKC systems can only provide many-to-one access control service, thus cannot meet the requirement for flexible data sharing. The new emerging cryptology systems including blockchain technology, secret sharing algorithm, attributed-based encryption, not only realize fine-grained access control mechanism, but also ensure data security.

報告人简介: Wenping Ma received the B.S. and the M.S. degrees in basic mathematics from Shaanxi Normal University, Xi’an, China, in 1987 and 1990, respectively, and the Ph.D. degree in communication and information system from Xidian University, Xi’an, China, in 1999. He was a Post-Doctorial Fellow with Chonbuk National University, Jeonju, South Korea, from 2003 to 2004, and acted as a senior visiting scholar in South Korea from 2004 to 2005. He is currently a Professor with the State Key Laboratory of Integrated Service Networks, School of Telecommunications Engineering, Xidian University, Xi’an, China. His research work mainly focuses on information theory, communication theory, error correcting code and information security.


告二:基于SM9数字签名算法的盲签名方案(何德彪 教授)112日下午15:30-1700

   要:SM9是由國家密碼管理局頒布的一種標識公鑰密碼算法,主要用于數字簽名、數據加密、密鑰交換以及身份認證等。盲簽名就是接收者在不讓簽名者獲取所簽署消息具體內容的情況下所采取的一種特殊的數字簽名技術,在電子現金、電子投票等多個領域有著廣泛應用。爲了推廣SM9算法在這些領域的應用,我們提出了一種基于SM9數字簽名算法的盲簽名方案,並給出了安全性證明。通過我們的方案可以産生SM9的盲簽名,保護了用戶的隱私。

報告人简介:何德彪,博士,武漢大學國家網絡安全學院教授,博士生導師。研究方向包括:應用密碼學、區塊鏈安全、雲計算安全、物聯網安全等。2009畢業于武漢大學數學與統計學院應用數學專業,獲理學博士學位。近年來,在IEEE TIFSIEEE TDSCScience China-Information Sciences等國內外著名期刊/會議上發表學術論文100余篇。主持國家自然科學基金、國家科技部“網絡空間安全”重點專項子課題、教育部博士點基金、湖北省自然科學基金等20余項科研項目。獲得教育部自然科學獎一等獎1項;獲得國際知名期刊IEEE Systems Journal2018年最佳論文獎;擔任中國計算機學會區塊鏈專委會常務委員、中國密碼學會學術工作委員會委員、中國密碼學會組織工作委員會委員和中國密碼學會青年工作委員會委員;擔任Mathematical Reviews特約評論員;擔任IET Wireless Sensor SystemsJournal of Medical SystemsComputers & Electrical Engineering等多個國際知名期刊的編委。

告三:Provably secure proactive secret sharing without the adjacent assumption(夏喆 副教授)112日下午17:00-1830

   要:Proactive secret sharing (PSS) not only shares the secret among a number of parties, but also divides the lifetime of the secret into many short time periods. The parties jointly update their secret shares in each time period, so that if the adversary cannot break into enough parties in a single time period, her compromised shares will become obsolete after the shares being updated. However, most of the existing PSS schemes require the adjacent assumption, i.e. if a party is corrupted during an update phase it is corrupted in both time periods adjacent to that update phase. In this talk, we demonstrate that this assumption not only hinders the security model to capture the mobile adversary’s abilities, but also prevents PSS schemes being used in many real-world applications. To solve this issue, we propose the first PSS scheme that is provably secure without the adjacent assumption。

報告人简介:夏喆,男,1982年7月出生,博士、武汉理工大学副教授、硕士生导师。2009年获得英国萨里大学(University of Surrey)博士学位,2009年至2013年在英国萨里大学从事博士后研究,2017年至2018年在澳大利亚伍伦贡大学(University of Wollongong)进行访问学习,主要研究方向为密码学和安全协议。近年来在TIFS、IET Information Security、ACISP、Indocrypt等国际期刊會議上發表學術論文40余篇,曾担任澳大利亚学术委员会(ARC)信息安全方向评审及ESORICS、EVT等国际学术会议程序委员会委员。目前担任中国计算机学会推荐国际期刊《Journal of Information Security and Application》的副主编及多个信息安全专刊的编委。
