UK-SPS Seminar 21st July 2021 - Confidential Computing

Title: Confidential Computing: Challenges Today and Opportunities Tomorrow

 An interesting talk on confidential computing by a distinguished speaker from the US (XiaoFeng Wang is a Professor at Indiana University and the chair of ACM SIGSAC).

Speaker: XiaoFeng Wang (Indiana University Bloomington)

Host: Liqun Chen (Surrey)


Abstract: The rampage of incessant cyber attacks have caused the disclosure of billions of users’ private data, shaking the Internet to its core. In response, various data privacy laws and regulations have emerged, forcing the industry to change their practice and bringing the demand for large-scale secure computing to the spotlight. Such a demand, however, cannot be met by the state-of-the-art cryptographic techniques, even with decades of effort, due to the overheads (speed, bandwidth consumption) they incur. To narrow the gap, recent years have seen rapid progress in hardware based trusted execution environments (TEE), such as Intel SGX, AMD SEV and ARM TrustZone, which enable efficient computation on encrypted data within a secure enclave established by a trusted processor. In this talk, I will present our research on understanding and addressing the security challenges in this new secure computing paradigm and enhancing its design to achieve scalability, for the purpose of supporting accelerated machine learning. Further I will present the big questions that need to be answered in the area and introduce our genome privacy competition as a synergic activity that helps move the science in this area forward.

Bio: Dr. XiaoFeng Wang is a James H. Rudy Professor at Indiana University, Director of IU’s security program, Co-director of IU’s Center for Security and Privacy in Informatics, Computing and Engineering, and Chair of ACM SIGSAC (special interest group on security, audit and control).  He also served as a PC Co-Chair for the ACM Conference on Computer and Communications Security (CCS), the ACM’s flagship security and privacy conference during 2018 and 2019.  Dr. Wang received his Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University.  He is considered to be among the most prominent system security researchers, a top author according to online statistics such as and system security circus, and a most influential scholar in security and privacy according to AMiner AI 2000. Dr. Wang is known for his high-impact research on security analysis of real-world systems and biomedical data privacy. Particularly, the projects he led on novel side channel analysis and discovery, payment and single-sign-on API integration, Android and iOS security and IoT protection have changed the way the industry built secure computing systems.
