The paper discusses a trust evaluation methodology for wireless sensor networks (WSNs) that addresses limitations of traditional cryptographic methods regarding code size, processing, and power consumption. It introduces a self-scrutiny and self-attestation model for nodes to assess their trust levels independently of network topology, demonstrating its effectiveness through actual implementations. The study highlights the robustness and consistency of the proposed algorithms against attack scenarios.
Node-Level Trust Evaluation in Wireless Sensor Networks
- 1. Node-Level Trust Evaluation in Wireless Sensor Networks ABSTRACT: Traditional cryptographic methods do not cater to the limitations of Wireless Sensor Networks WSNs primarily concerning code size, processing time, and power consumption. The study in this paper enumerates the security primitives in WSNs and accentuates the strength of trust evaluation as a security solution within the WSN precincts. The paper proposes a trust evaluation methodology that evaluates a node-level trust by using an internal resource of a node. It is completely mediating technique which is independent of network topology and second-hand information. The Challenge-Response model enables a node to evaluate trust for itself; and with its peer-node/s with which it intends to interact using the proposed Self-Scrutiny and Self-Attestation algorithms, respectively. The efficacy of the proposed software-based methodology and the algorithms is demonstrated with the actual implementation on sensor nodes. The ability to counter attack-scenarios along with the analysis exhibit the merit of the proposed work. The average values of the observed results illustrates the consistency and robust performance of the proposedtrust evaluation algorithms.
