The Internet of Things (IoT) is a very abundant source of data, as well as a source of many vulnerabilities. A significant challenge is preparing security solutions to protect IoT nodes' resources and the data exchanged. The difficulty usually stems from the insufficient resources of these nodes in terms of computing power, memory size, range energy resource, and wireless link performance. The paper presents the design and demonstrator of a system for symmetric cryptographic Key Generating, Renewing, and Distributing (KGRD). The system uses the TPM 2.0 hardware module to support cryptographic procedures, including creating trust structures, key generation, and securing the node's exchange of data and resources. Clusters of sensor nodes and traditional systems can use the KGRD system to secure data exchange in the federated cooperation of systems with IoT-derived data sources. The transmission medium for exchanging data between KGRD system nodes is the Message Queuing Telemetry Transport (MQTT) service, which is commonly used in IoT networks.
物联网(IoT)是一个非常丰富的数据来源,也是许多漏洞的来源。一个重大挑战是准备安全解决方案来保护物联网节点的资源和交换的数据。这种困难通常源于这些节点在计算能力、内存大小、范围能源资源和无线链路性能方面的资源不足。本文提出了一种用于对称密码密钥生成、更新和分发(KGRD)的系统的设计和演示。该系统使用 TPM 2.0 硬件模块来支持加密过程,包括创建信任结构、生成密钥和保护节点交换数据和资源。传感器节点集群和传统系统可以使用 KGRD 系统来保护具有物联网派生数据源的系统联邦合作中的数据交换。在 KGRD 系统节点之间交换数据的传输介质是消息队列遥测传输(MQTT)服务,它在物联网网络中被广泛使用。
