Abstract: The extensive application of the Internet of Things in various fields has caused a spurt of equipment growth. Terminal device authentication has become a key issue for the security management and control of IoT access. At present, blockchain technology has begun to be applied to the security of the Internet of Things business, but there is no effective solution for device authentication based on the blockchain. Based on block header synchronization verification and Simple Payment Verification (SPV) technology, this paper proposes a device authentication method based on blockchain transaction verification, which reduces the risk of leakage of key credentials during the communication process, and reduces the block chain’s transaction confirmation through the consensus mechanism Waiting for the delay provides a reliable and efficient security access mechanism for IoT devices.

摘要： 物联网在各个领域的广泛应用，造成设备井喷式增长．终端设备认证成为物联网接入安全管控的关键问题．目前，区块链技术已开始应用于物联网业务安全，但基于区块链的设备认证方面尚未出现有效的方案．本文基于区块头同步验证与简单支付验证（SPV）技术，提出基于区块链交易验证的设备认证方法，减少密钥凭证在通信过程中泄漏的风险，降低区块链通过共识机制进行交易确认的等待时延，为物联网设备提供可靠、高效的安全接入机制．
