2019 · 12th ACM Conference on Security and Privacy in Wireless and Mobile Networks (WiSec)
- Perspective
Research question
What does the paper try to establish?
What must the remote-attestation community add to manual protocol reasoning and ad hoc implementation to obtain stronger confidence in claimed security, safety, and robustness?
Central answer
What is the proposed answer?
The position paper argues for computer-aided specification and verification of RA protocols and hardware/software architectures, followed by correct-by-construction synthesis of executable components. It supports the agenda with concrete prior-design failures and identifies open obligations in property completeness, end-to-end verification, synthesis, and group attestation.
Full paper abstract
Abstract
Remote Attestation (RA) of embedded/smart/IoT devices is a very important issue on today’s security landscape. RA enables a verifier to measures the current internal memory state of an untrusted remote device (prover). RA helps the verifier establish a static or dynamic root of trust in prover. Despite much prior work, state-of-the-art RA techniques unfortunately still lack any solid foundation and offer no ironclad security, safety or robustness guarantees. This paper argues that computer-aided formal verification, and synthesis of executables, of RA protocols and hybrid (software-hardware) architectures is required and currently unaddressed. We believe that this is achievable with current (computer-aided) formal methods frameworks and tools, and that this can help advance and mature RA research if used to establish more rigorous and clear security arguments. To support our opinion, we highlight several examples where subtle issues were missed in the design and security analysis of RA techniques. Despite deceptive simplicity of such protocols, manual analyses and ad hoc implementations often lead to over-simplification of (and subsequent glossing over) important details in the underlying processor and system architectures. Computer-aided formal verification forces a more scrupulous and disciplined consideration of such details, since, otherwise, verification simply fails. The key objective of the research direction we propose is to increase confidence in correctness and security guarantees of current and future RA techniques and their implementations.

A formal-methods agenda for remote attestation
A position paper arguing that RA security claims need machine-assisted models, proofs, and synthesized implementations, supported by failure case studies and a four-part agenda.

argued positionSpecify RA requirements and threat models precisely, verify protocol and hardware/software components with computer aid, prove their composition, and synthesize executable artifacts from checked descriptions.

scope Scope of the argument
explicitThe discussion focuses on challenge-response measurement against a remote software adversary; completeness of the initial security definition itself and physical adversaries are explicitly orthogonal or excluded.

premise Why RA is a tractable first target
arguedRA has only a few messages and basic primitives such as HMAC, yet hybrid implementations expose processor, memory, interrupt, and control-flow details that manual abstractions routinely miss.

evidence Non-instantaneous interrupt control
architecture caseOn some MCUs, enabling or disabling interrupts spans cycles and can itself be interrupted, so a paper assumption of instantaneous atomicity may block formal verification or security.

evidence Self-attestation denial of service
design caseA return-address API can point back to attestation entry and combine with enforced atomicity to trap a device in an endless attestation loop; a termination proof would expose the corner case.
