基于双伪随机序列的物联网安全蜜罐节点研究

Research on Secure Honeypot Node for IoT based on Double Pseudo-Random Sequences

成功部署物联网的基础是安全性,而目前由于部署的特点使得边缘节点成为确保物联网安全性中最薄弱的环节之一。现有的加密算法与物联网边缘节点计算能力弱和占用资源有限等特点相矛盾,导致边缘节点很难执行复杂度高的非对称或对称加密算法,因此需要设计一种对能源需求和计算复杂都较低的边缘节点保护机制。现提出一种基于双伪随机序列的物联网安全蜜罐节点,该节点具有与物联网中其他节点相同的功能,同时承担蜜罐功能。一旦其被攻击者攻击并利用,那么物联网管理中心会立刻发现该节点被劫持,从而发挥物联网边缘节点的安全警戒作用。

The foundation of successful IoT deployment is security,and currently,edge nodes have become one of the weakest links in ensuring IoT security due to their deployment characteristics.Existing encryption algorithms contradict the weak computing power and limited resources of IoT edge nodes,making it difficult for edge nodes to execute asymmetric or symmetric encryption algorithms with high complexity.Therefore,a protection mechanism for edge nodes with low energy demand and computational complexity is needed.In this paper,we propose an IoT security honeypot node based on double pseudo-random sequences,which has the same functions as other nodes in the IoT and is also burdened with the honeypot function,so that once it is attacked and exploited by attackers,the IoT management center will immediately find that the node is hijacked,thus playing the security vigilance role of the IoT edge node.
