Rigorous Micro-Verification of Legacy Embedded Software Systems

Objective

Formal verification of software systems can, in theory, provide mathematical certainty about their correctness or security. However, current approaches imply a significant, cross-cutting impact on systems' architecture, legacy implementations, and even their long-term engineering processes and developer staffing. In this project, we develop an alternative approach for realistic embedded systems, based on micro-verification and results from our UniversalContracts ERC project. Relying on commodity CPU security primitives, micro-verification allows us to restrict the formal verification of systems to a small, properly encapsulated TCB, combined with a largely unmodified legacy software stack and its existing software engineering process. Formal characterisations of the security properties of real ISAs from the UniversalContracts project will allow us to still provide full-stack guarantees, rigorously validated against official ISA semantics. The resulting approach promises (1) low-cost verification of application-specific security properties, (2) rigorous foundational guarantees in realistic system models, but also (3) compatibility with organisations' existing legacy software, non-expert developer staff and engineering process. Based on industry requirements and feature prioritisation, we intend to produce a proof-of-concept (PoC) demonstrator system, use industry input to identify and prioritise missing features, evaluate the market potential, and identify further research opportunities.
