应广西云计算与大数据协同创新中心、广西云安全与云服务工程技术研究中心、广西云计算与复杂系统高校重点实验室、计算机科学与工程学院共同邀请,澳大利亚卧龙岗大学穆怡教授、电子科技大学禹勇博士将于1月12日来我校讲学,欢迎全校师生踊跃参加。具体安排如下:

  学术报告一:
时间:1月12日(周二)下午14:30-15:50
地点:金鸡岭校区10教516报告厅
报告人:Professor Yi Mu
题目:Block-level Message-Locked Encryption for Secure Large File Deduplication
  摘要:Deduplication is a popular technique widely used to save storage spaces in the cloud. To achieve secure deduplication of encrypted files, Bellare et al. formalized a new cryptographic primitive named Message-Locked Encryption (MLE) in Eurocrypt 2013. Although an MLE scheme can be extended to obtain secure deduplication for large files, it requires a lot of metadata maintained by the end user and the cloud server. In this talk, a new approach is introduced to achieve more efficient deduplication for (encrypted) large files, named as Block-Level Message-Locked Encryption, which can achieve file-level and block-level deduplication, block key management, and proof of ownership simultaneously using a small set of metadata. The scheme can be easily extended to support proof of storage, which makes it multi-purpose for secure cloud storage. 
报告人简介:Professor Yi Mu received his PhD from the Australian National University in 1994. He is currently a full professor and Director of Centre for Computer and Information Security Research at University of Wollongong, Australia. He was the Head of School of Computer Science and Software Engineering at University of Wollongong during 2011-2015. Prior to joining University of Wollongong, he was a senior lecturer in the Department of Computing, Macquarie University. He also worked in the Department of Computing and IT, University of Western Sydney as a lecturer. He has been with the University of Wollongong since 2003. His current research interest includes cryptography, information security and quantum cryptography. He has published over 370 research papers, including over 140 journal papers. His research has been funded by Australian Research Council and industry. He has served as program chair and member of program committee over 200 conferences including ACM CCS, ESORICS, ACISP, AisaCCS, etc. and is currently a member of the steering committees of AsiaCCS, CANS and ProvSec. Professor Yi Mu is the editor-in-chief of International Journal of Applied Cryptography and serves as associate editor for nine other international journals including Information Sciences, The Computer Journal, etc. He is a senior member of the IEEE.

  学术报告二:
时间:1月12日(周二)下午15:50-16:50
地点:金鸡岭校区10教516报告厅
报告人:禹勇博士
题目:基于身份的云数据审计
  摘要:云存储服务大大减轻了用户的数据管理负担。然而,云服务提供商不是完全可信的,数据在云端是否完好保存即云数据完整性成为用户最大的担忧。云数据审计协议是一种在无需下载云数据的前提下实现云数据完整性检测的轻量型协议。报告介绍简化密钥管理的云数据审计协议:基于身份云数据审计协议;内容包括对现有协议的分析,以及提出的一般性构造和具有数据隐私保护的新型构造。
