<p>A brief introduction to the room and to the sessions.</p>
This year's TEE devroom will again be a full-day virtual event with an impressive lineup! The day will be roughly divided into session blocks grouping related talks as follows:
10h00-12h25: TEE attacks, defenses, and enclave shielding runtimes
featuring an enclave exploit analysis, Guardian, Gramine, Enarx, and Veracruz
13h25-14h40: Emerging TEEs and best practices
featuring logging in confidential computing, secure boot, and ARM CCA
14h55-16h10: OS and and page-based isolation
featuring FlexOS, Intravisor, and EDP for AWS Nitro
16h30-17h30: Wrap up and discussion on process-based abstractions for VM-based environments
we wrap up the day with a live presentation and a following discussion

<p>Intel SGX provided a mechanism to better isolate user-level software from attackers. However, attackers will still use various methods to attack SGX and user’s Enclaves. And user’s code inside Enclave may also have bugs, which can be leveraged by the attackers. We are from intel SGX SDK team, we have conducted security analysis and pen-test for SGX Enclave (based on SGX SDK) during the past 10+ years. We want to summarize some past exploits we encountered in our daily work and what's the ...

<p>Gramine (formerly called "Graphene") is a lightweight library OS, designed to run a single Linux application in an isolated environment. Currently, Gramine runs on Linux and Intel SGX enclaves on Linux platforms. With Intel SGX support, Gramine can secure a critical application in a hardware-encrypted memory region and protect the application from a malicious system stack with minimal porting effort ("lift and shift" approach).</p> <p>Several major events happened to the Gramine project in ...

<p>The Enarx project reached a huge milestone: its first official release, featuring WebAssembly runtime. WebAssembly and Confidential Computing are a great match because WebAssembly offers developers a wide range of language choices, it works across silicon architectures, and it provides a sandboxed environment. This presentation will highlight the benefits of WebAssembly to Confidential Computing and showcase some demos.</p>

<p>Veracruz is a framework for designing and deploying privacy-preserving computations amongst a group of mutually mistrusting individuals. Veracruz uses strong isolation technologies, such as AWS Nitro Enclaves, Arm CCA Realms, and the high-assurance seL4 hypervisor, to provide a safe, neutral ground, within which a sandboxed WebAssembly program executes. Recent enhancements to Veracruz have made it possible to support larger, more complex privacy-preserving computations: we have adopted the ...

<p>The confidentiality and integrity guarantees offered by Intel SGX enclaves can be easily thwarted if the enclave has not been properly designed. Its interface with the untrusted software stack is a perhaps the largest attack surface that adversaries can exploit; unintended interactions with untrusted code can expose the enclave to memory corruption attacks, for instance.</p> <p>We have proposed a notion, called orderliness, that embodies good practice set out by academic papers and the ...
