ARCADIS: Asynchronous Remote Control-Flow Attestation of Distributed IoT Services

Remote attestation (RA) is a security mechanism that verifies the trustworthiness of remote IoT devices. Traditional RA protocols aim to detect presence malicious code in static memory device. In domain, research currently following two main directions: Dynamic and Swarm RA. schemes intend runtime attacks hijack control-flow execution running program without injecting new into memory. On other hand, swarm focus on attesting efficiently effectively large number However, existing do not perform dynamic asynchronous networks. This paper proposes protocol for Asynchronous Control-Flow Attestation Distributed Services (ARCADIS). extends state-of-the-art by detecting devices have (directly or indirectly) been maliciously influenced distributed services. The has simulated Wismote sensors Contiki emulator. conducted experiments confirm feasibility ARCADIS demonstrate its practicality small
