(VIRTUAL) Abstracting TEE Silicon Implementations with Shims - Nathaniel McCallum & Harald Hoyer, Profian

Enarx provides a WebAssembly runtime across multiple TEE implementations, currently targeting Intel SGX and AMD SEV, with plans for others in the future (including from Arm and IBM). The various architectures presented by the silicon vendors are very diverse, and creating a design that allows implementations on the various platforms has presented a variety of challenges. In this talk, Nathaniel & Harald will concentrate on the shim layers below the WebAssembly runtime, and the approaches the project has taken to support Intel SGX and AMD SEV in particular. They will discuss design trade-offs and choice of language for implementation. They will also talk about pitfalls which presented themselves and what implementations on future silicon is likely to require, based on information already available in the public domain.
