Secure Random Key Distribution Scheme for Industrial wireless Sensor Systems Against Node Replication Attacks

Computer Engineering

ABSTRACT Since node replication attacks are conducted at the physical layer, they are difficult to defend against and have become increasingly common since the widespread adoption of wireless sensor networks in smart industrial systems. To address this issue, we propose a new method of defence against the attack by means of a secure random key distribution scheme (SRKD). To help identify and remove harmful nodes, we use a voting mechanism in conjunction with a locally tailored algorithm. To further protect against the replication attack, we alter the significance of the parameter s. In addition, when the number of network nodes reaches 200, the detection ratio of replicate nodes is greater than 90%, demonstrating the safety and efficacy of our scheme. When compared to other, more advanced schemes, SRKD shows superior storage and communication efficiency.
