The Eighth International Workshop on Security in Blockchain and Cloud Computing (SBC)

To be held in conjunction with the 15th ACM Asia Conference on Computer and Communications Security (ASIACCS)
October 6, 2020, Virtual Online Conference (GMT+8)


Virtual Conference Notice

Due to persisting concerns over travel safety in the wake of COVID-19, the SBC workshop will take place as a virtual event, as part of the AsiaCCS 2020 main conference.

Call for Papers

Cloud computing has emerged as today's most exciting computing paradigm shift in information technology. With the efficient sharing of abundant computing resources in the cloud, users can economically enjoy the on-demand high quality cloud applications and services without committing large capital outlays locally. While the cloud benefits are compelling, its unique attributes also raise many security and privacy challenges in areas such as data security, recovery, privacy, access control, trusted computing, as well as legal issues in areas such as regulatory compliance, auditing, and many others. To implement secure and privacy-aware environments which can provide on-demand computing and high-quality service for cloud users is extremely urgent. Blockchain is another paradigm shift and drew a lot of recent attentions from both academia and industry. Moreover, blockchain and cloud have many interplays.

Building on the success of 7 versions of the International Workshop on Security in Cloud Computing (SCC), held often with ACM AsiaCCS, we plan this year to rebrand it to include blockchain as well and organize this workshop again for the eighth edition. This workshop is intended to bring together researchers, developers, and practitioners in security, privacy and mobile computing communities. We will encourage submissions on all theoretical and practical aspects, as well as experimental studies of deployed systems.

Topics of interests include (but are not limited to) the following subject categories:

Invited Talk1
9:00 - 10:00

This talk highlights challenges and opportunities for trustworthy AI with a focus on privacy attacks and countermeasures. AI and machine learning have no future if their privacy and security concerns are not addressed. Machine learning models could hide malicious code or backdoors, and leak private information about users. We will explore inference attacks against machine learning models and frameworks (e.g., federated learning), and set out the requirements for privacy-preserving AI systems.

Speaker:

Giuseppe Ateniese is the Farber Endowed Chair in Computer Science and department chair at Stevens Institute of Technology. He was with Sapienza-University of Rome (Italy) and Assistant/Associate Professor at Johns Hopkins University (USA), and one of the founders of the JHU Information Security Institute. He was a researcher at IBM Zurich Research lab (Switzerland) and scientist at the Infor- mation Sciences Institute of the University of Southern California (USA). He also briefly worked as visiting professor at Microsoft in Redmond (USA). He received the NSF CAREER Award for his research in privacy and security, and the Google Faculty Research Award, the IBM Faculty Award, and the IEEE CISTC Technical Recognition Award for his research on cloud security. He has contributed to areas such as proxy re-cryptography, anonymous communication, two-party computation, secure storage, and provable data possession. He is currently working on cloud security and machine learning applied to security and intelligence issues for which he received an IBM SUR Award. He is also investigating new security applications for decentralized computing based on the blockchain/bitcoin technology.

 
Invited Talk2
10:00 - 11:00

We increasingly live in a software-defined world where systems that were once implemented as rigid control capabilities or fixed function hardware systems are now highly programmable through software interfaces that decouple underlying details and offer remote control and centralized management. Blockchain and cloud computing systems are early examples of embracing software-defined system designs.

We argue that we should further leverage software-defined principles to make security programmable, thus also make this software-defined world more secure. We will use two case studies to demonstrate how programmable security can be achieved on software-defined networking (SDN) and blockchain systems, respectively.

Speaker:

Dr. Guofei Gu is a professor in the Department of Computer Science & Engineering at Texas A&M University (TAMU). Before coming to Texas A&M, he received his Ph.D. degree in Computer Science from the College of Computing, Georgia Institute of Technology. His research interests are in network and systems security.

Dr. Gu is a recipient of 2010 NSF CAREER Award, 2013 AFOSR Young Investigator Award, 2010 IEEE S&P Best Student Paper Award, 2015 ICDCS Best Paper Award, Texas A&M Dean of Engineering Excellence Award, and Presidential Impact Fellow Award. He is an active member of the security research community and has pioneered several new research directions such as botnet detection/defense and SDN security. Dr. Gu has frequently served on the program committees of top-tier security conferences such as IEEE S&P, ACM CCS, USENIX Security, and NDSS. He is an IEEE Fellow, an ACM Distinguished Member, an Associate Editor for IEEE Transactions on Information Forensics and Security (T-IFS), and the Steering Committee co-chair for SecureComm. He recently co-chaired the 2018 NSF Workshop on Programmable System Security in a Software Defined World. He is currently directing the SUCCESS Lab at TAMU.
