【Abstract】The development of Internet of Things (IoT) technology leads to the continuous growth of IoT devices. Due to the characteristics of resource constraints and interdependencies, IoT devices are vulnerable to many security issues. Remote attestation can verify the integrity of remote devices. However, there are some problems that exist, such as only verifying the integrity of static and runtime data, attestation evidence growing proportionally to the number of services, resulting in significant increase in runtime overhead. Therefore, this article proposes a blockchain-assisted integrity attestation scheme for distributed dependency IoT services. The scheme builds a distributed service integrity model capable of measuring the integrity of both static data and runtime data of distributed IoT services. In addition, we propose a secure and trusted blockchain query mechanism, which can effectively resist tampering or storage errors in the database data of a certain node in the blockchain. Furthermore, a two-way authentication distributed service integrity attestation protocol is designed to protect the communication security between participants without excessive performance overhead. We demonstrate the security of the attestation protocol with automated validation of Internet security protocols and applications. The feasibility and performance of the proposed scheme are verified by simulating the Wismote sensor using the Cooja simulator.
