On May 3rd, 2024 at 11.30 am a new appointment of NECSTFridayTalk series titled: "Confidential Computing - A Security Overview and Future Research Directions" will take place at DEIB NECSTLab Meeting Room (Building 20) and on line by Zoom.
During this talk, we will have, as speaker Alessandro Bertani, PhD student in Information Technology at DEIB, Politecnico di Milano on the following about the talk: 

By performing computations within hardware-based Trusted Execution Environments (TEEs), Confidential Computing protects data in use, which has been a longstanding challenge in data security. This talk provides an overview on Confidential Computing technologies, with a focus on security implications and recent developments. We begin with an introduction to Confidential Computing, its principles, and its relevance to data security. We outline the threat model for Confidential Computing, considering in-scope and out-of-scope attack vectors. We analyze published attacks, their complexities, and mitigation approaches in the context of Confidential Computing. We analyze data security within TEEs, including encryption, access control, and memory protection mechanisms across different technologies (e.g., Intel TDX, AMD SEV, Arm CCA). Finally, we explore future research directions, including the challenges related with the integration of TEEs and emerging technologies like Compute Express Link (CXL) to further enhance data-in-use security and the use of Confidential Computing in Machine Learning applications.

The NECSTLab is a DEIB laboratory, with different research lines on advanced topics in computing systems: from architectural characteristics, to hardware-software codesign methodologies, to security and dependability issues of complex system architectures.

Every week, the “NECSTFridayTalk” invites researchers, professionals or entrepreneurs to share their work experiences and projects they are implementing in the “Computing Systems”.
