If you’re designing a project where security is uppermost, but you want to make it easy to use and compatible with multiple platforms (existing and future), what principles should you follow, and how do they translate into an architecture and actual code. We’ll present the 10 security design principles of the Enarx project, and discuss why they led us to where we are today: a Rust-based open source project with a WebAssembly run-time.

In this presentation we will introduce Veracruz, a project recently adopted by the Confidential Compute Consortium, exploring how efficient, collaborative computations between mutually distrusting parties can be developed using a mixture of hardware- and software strong isolation mechanisms. Veracruz uses Arm TrustZone, Intel SGX, AWS Nitro Enclaves, or the high-assurance seL4 microvisor, to provide a "neutral ground" within which a collaborative computation takes place, shielded from prying or ...

Graphene is a lightweight library OS, designed to run a single Linux application in an isolated environment. Currently, Graphene runs on Linux and Intel SGX enclaves on Linux platforms. With Intel SGX support, Graphene can secure a critical application in a hardware-encrypted memory region and protect the application from a malicious system stack with minimal porting effort. This talk will discuss the design, implementation, features, lessons learned, and the current status of the project. The ...

Existing attestation schemes require pre-signed enclave images and provide few means of including runtime-dependent configuration data (like report data, enclave held data, configid). In multi-party settings in which the parties may not always fully trust each other, attestation of multiple pieces of code or data images via these means is cumbersome and inefficient. For example, consider the case of a secure cloud service running a JavaScript interpreter, which interprets a third-party script, ...

In this talk, we present an open-source framework to develop heterogeneous, distributed enclaved applications. The main feature of our framework is to provide a high level of abstraction over the platform-specific TEE layer and over the secure communication between different modules, leaving to a developer only the task to write the application’s logic. We provide a notion of event-driven programming to develop distributed enclave applications in Rust and C for heterogeneous TEEs, including ...

Previous work such as Plundervolt has shown that software-based undervolting can induce faults into Intel SGX enclaves and break their security guarantees. However, Intel has addressed this issue with microcode updates. We later discovered that there is a physical connection on the motherboard which allows us to control the voltage and conduct fault injection. In this talk, we will present a low-cost device: Voltpillager, which use this physical connection to break the guarantees provided by SGX ...
