物联网(IoT)允许计算和传感设备通过互联网互联，使它们能够发送和接收数据。物联网的应用范围从智能家居到可穿戴设备。由于设备之间交换的信息的关键和敏感性质，物联网系统具有很高的安全要求。本文定义了一种由非对称密码和对称密码组成的方案来保护物联网系统中设备之间的通信。与简单地使用非对称加密算法相比，对称和非对称加密技术的组合减少了加密时间。每次使用随机密钥进行对称加密解决了会话密钥分发问题，并加强了对称加密方法。
Internet of Things (IoT) allows the interconnection of computing and sensing devices over the Internet, allowing them to send and receive data. The applications of IoT range from Smart Home to Wearable devices. An IoT system has high security requirements, owing to the critical and sensitive nature of the information exchanged between devices. In this paper, a schematic consisting of Asymmetric and Symmetric cryptography is defined to secure the communication between the devices in an IoT system. The combination of both Symmetric and Asymmetric cryptography reduces encryption time in preference to simply using an Asymmetric cryptographic algorithm. The use of random keys for Symmetric encryption each time solves the issue of session-key distribution and strengthens the symmetric encryption approach.
