Abstract: In this research paper, the positions of sensor nodes are used for generating their public keys. In a wireless sensor networks (WSN), the nodes observe the environment in their vicinity and send the position specific data to the sink. Since the position and sensed data of a sensor are linked up to each other, the sensor position can be used as its unique public key. Multivariate cryptography offers a lightweight alternative to public key cryptography for sensor networks and position as public key can enhance its viability for WSN. In this study, we proposed a position-based multivariate cryptosystem for WSN that verifies the position of the sensor node and also prevented from the collusion attack. The performance and security analysis of the proposed scheme demonstrates that reduce storage overhead, communication overhead and prevent collusion attack in various contexts are possible within lightweight computational constraints.
Keywords: sensor node positioning; multivariate cryptosystems; network security; wireless sensor networks; WSNs; cryptography; collusion attack.
