Proven Embedded WebAssembly runtime in SPARK
AdaCore: Helping Developers Build Software that Matters
Everything we do at AdaCore is centered around helping developers build safe, secure and reliable software.
For over 25 years, we've worked with global leaders across the military and civil avionics, defense systems, air traffic management/control, space, railway, and financial services industries, building tools and providing services that ease the complex and difficult process of developing high-integrity software. As the need for truly secure and reliable applications expands into industries such as automotive, medical, energy, and IOT, we’re advancing our time-tested technologies to bring expertise and services to help a whole new generation of developers. Through our subscription-based business model and dedicated services arm, we have worked with hundreds of customers over the year on thousands of projects.
Our 150 experts worldwide in the US (New York), France (Paris, Toulouse, Grenoble and Vannes), Germany, the UK, and Estonia, all play a role in developing state-of-the-art technologies to meet the challenges of building the highest grade of software.
Joining AdaCore is about joining a culture of innovation, openness, collaboration and dependability, which defines how we work together, with our customers and partners.
The sandboxed nature of WASM is an important property for security. However, for this property to hold the runtime must be free of defects and vulnerabilities. At the same time, the correctness of WASM instruction decoding and interpretation is absolutely essential for its trustworthiness.
The goal of this internship is to explore the use of formal verification in the implementation of an embedded WASM run-time. Using AdaCore’s industry ready formal verification solution called SPARK, you will implement a minimal WASM interpreter and prove the absence of vulnerabilities. In a second phase, you will push the proof to include functional correctness of the WASM execution.
Get a first understanding of the WebAssembly technology
Get a first understanding of the SPARK technology
Implement a first minimal version of a WASM runtime
Adapt the first implementation for formal verification
Push the formal verification into functional correctness
Write a blog post to communicate the effort to the WASM and SPARK communities
Possible extensions to this list could include performance comparison with existing WASM runtimes, and optimisation
Skills required or Nice to have:
Interest for low-level/system programming
Interest for formal verification
Knowledge of WebAssembly (nice to have)
Knowledge of CPU emulation and or virtual-machines (nice to have)
Curiosity and interest for technical innovation
Will and ability to work autonomously
Timeframe & Location:
- During 2024 – 6 months
- Paris, France
