【Abstract】The Internet of things (IoT) is a heterogeneous network, and devices produced by different manufacturers lack trust and coordination mechanisms, so they are vulnerable to attacks. Blockchain can provide credible communication at a low cost for IoT nodes. However, the classic digital signature algorithms commonly used in blockchain are no longer secure enough against quantum computing attacks. Given that the emergence of universal quantum computers is just around the corner, we propose a quantum-assisted blockchain of things (QBoT) based on quantum signature. This scheme can protect IoT systems from computation-based attacks and provide more secure communication assurance between nodes. Finally, we analyze the possible attacks on the IoT, and the results show that our proposed scheme can guarantee the security of common IoT attacks. Furthermore, compared with previous quantum-assisted blockchain schemes, QBoT is more efficient and scalable.
