Sensor nodes play a major role in IoT environment, and each sensor is a peer to peer networking. Due to limited physical size, IoT sensor nodes must have light-weight authentication protocol. The Internet of Things (IoT) is a collection of various technical elements. It is expected that interworking between heterogeneous terminals, networks, and applications. They will accelerate through the liberalization of the IoT platform. As a result, many technical and administrative security threats will arise in the IoT environment. Sensor node protocols must be light-weight and secure. As IoT devices are used for various purposes, for some devices that require performance, the OS with a high-performance chipset that works, most passwords protocol. However, to turn on / off the lights IoT devices that perform simple tasks such as based on a low-performance chipset with no OS running. If it does not support encryption protocol or certificate, then it is vulnerable, and it does not have enough performance to handle. Therefore, in this paper, Block-chain-based IoT device is proposed to get a more secure authentication scheme.

基于区块链的基于P2P网络的物联网（IoT）传感器节点认证

传感器节点在物联网环境中起着重要作用，每个传感器都是对等网络。由于物理尺寸有限，IoT传感器节点必须具有轻量级的身份验证协议。物联网（IoT）是各种技术元素的集合。期望异构终端，网络和应用程序之间的互通。它们将通过物联网平台的开放而加速。结果，在物联网环境中将出现许多技术和管理安全威胁。传感器节点协议必须轻巧且安全。由于IoT设备用于各种目的，对于某些需要性能的设备，带有可工作的高性能芯片组（大多数密码协议）的OS。然而，打开/关闭执行简单任务（例如基于没有运行操作系统的低性能芯片组）的物联网设备。如果它不支持加密协议或证书，则容易受到攻击，并且没有足够的性能来处理。因此，本文提出了一种基于区块链的物联网设备，以获得一种更加安全的身份验证方案。
