应我校无线网络安全技术国家工程实验室邀请,西安电子科技大学陈晓峰、王保仓,意大利米兰理工大学Achilles Pattavina教授3位专家学者将于9月20日、22日来我校做信息安全系列学术讲座及座谈会,欢迎广大师生参加!报告及座谈会的具体安排如下:
报告地点:长安校区通信与信息工程学院大楼106室
报告一:可验证数据库更新技术研究(陈晓峰教授)2017年9月20日(周三)15:30—17:00
摘要:可验证数据库(VDB)能够使资源受限的用户将大型的数据库安全外包给不信任的服务器,并能够通过设定新的值更新数据库和恢复数据库的记录,同时任何服务器试图篡改数据的行为都将被将被检测到。本报告主要介绍如何设计支持全操作更新的VDB方案。
报告人简介:陈晓峰,西安电子科技大学网络与信息安全学院教授。教育部青年长江学者,“新世纪优秀人才计划”入选者,科技部“中青年科技创新领军人才”,陕西省密码学专业教学团队带头人。现任西安电子科技大学综合业务网理论及关键技术国家重点实验室信息安全研究中心主任。主要研究领域为密码学和云计算安全,已在重要国际会议和期刊发表学术论文100余篇,担任IEEE TDSC、SCN、TELS等著名国际期刊的编辑,AisaCCS 2016、NSS 2014等多个国际会议的大会主席。获2016年度中国密码学会密码创新奖以及陕西省青年科技奖。主持和完成NSFC等10余项科研项目。
报告二:对一个对称全同态密码的攻击(王保仓教授)2017年9月22日(周五)10:00—11:00
摘要:最近,Lichun Li等人提出了一个对称的全同态加密算法,并使用该算法构造了一个隐私保护的数据库关联规则挖掘外包协议。基于连分式算法,证明了Lichun Li等人的全同态加密算法是不安全的。给定一系列明密文对,可以在多项式时间内恢复Lichun Li等人的全同态加密算法的解密密钥。

报告三:Impact of Cloud RAN on 5G Access‐Aggregation Networks(Achille Pattavina 教授)2017年9月22日(周五)11:00—12:00
摘要:5G mobile networks are expected to meet a set of extremely‐challenging performance requirements, in terms of enhanced throughput, increased coverage, reduced latency and power consumption. To meet such requirements, a promising solution for future 5G networks is the recently proposed Centralized‐Rad Access Network (C‐RAN), supported by optical aggregation based on Wavelength Division Multiplexing. C‐RAN is expected to provide significant CapEx/OpEx savings, deriing from the consolidation of processing facilities among different Digital Units (DU). In view of the massive small cells deployment and traffic increase envisioned for 5G, fronthaul transport between DUs and Radio Units (RU) is expected face serious scalability issues. Thus, alternative midhaul RAN splits are now under analysis to reduce the required network capacity.
报告人简介:Achille Pattavina received the Dr. Eng. degree in Electronic Engineering from University of Rome (Italy) in 1977. He was with the same University until 1991, when he moved to “Politecnico di Milano”, Milano (Italy), where he is Full Professor since 1995. He has been author/coauthor of more than 300 papers in the area of communications systems and networks and of two books: Switching Theory, Architectures and Performance in Broadband ATM Networks (New York: Wiley, 1998), Communication Network: Networking and Internet (McGraw-Hill, 2nd ed., 2007, in Italian). He has been coordinator of national and international research activities, including European Union funded projects. He has been Editor for Switching Architecture Performance of the IEEE Transactions on Communications from 1994 to 2011 and Editor-in-Chief of the Wiley European Transactions on Telecommunications from 2001 to 2010. His current research interests are in the areas of data center and cloud computing, software defined networking, optical networks, switching theory, broadband convergent access/metro networks.
