The 3rd AEGIS Symposium on Cyber Security

The Annual rEading Group in Information Security (AEGIS) Symposium is an annual symposium held online by a group of researchers of Privacy and Security in Computer Science.

In 2023, the 2nd AEGIS Symposium hosted 12 talks given by a variety of security researchers in security, covering a wide range of topics with a highlight on LLM security. The 2024 symposium will be the 3rd symposium of the AEGIS symposia series.

As usual, the 3rd AEGIS Symposium will be delivered virtually in Zoom. For any additional questions, please contact the organization committee.

Important News:

We have finalized the presenters this year, featuring 12 talks in four sessions. The topics of the presentation will be finalized in mid June. Looking forward to see you in AEGIS 2024!

Abstract:

The recent development of Trusted Execution Environment has brought unprecedented opportunities for confidential computing within cloud-based systems. Among various popular cloud business models, serverless computing has gained dominance since its emergence, leading to a high demand for confidential serverless computing services based on trusted enclaves. However, the issue of cold start overhead significantly hinders its performance, as new enclaves need to be created to ensure a clean and verifiable execution environment. In this paper, we propose a novel approach for constructing reusable enclaves that enable rapid enclave reset and robust security with three key enabling techniques: enclave snapshot and rewinding, nested attestation, and multi-layer intra-enclave compartmentalisation. We have built a prototype system for confidential serverless computing, integrating OpenWhisk and a WebAssembly runtime, which significantly reduces the cold start overhead in an end-to-end serverless setting while imposing a reasonable performance impact on standard execution.
