An Encrypted Trust-Based Routing Protocol
This addresses privacy issues in dynamic ad-hoc networks, but appears incremental as it builds on existing trust-based routing with encryption.
The paper tackles the privacy challenges in trust-based routing protocols for ad-hoc wireless networks by proposing a novel protocol based on fully homomorphic encryption, enabling nodes to securely evaluate and share trustworthiness of routes without compromising privacy.
The interest in trust-based routing protocols has grown with the advancements achieved in ad-hoc wireless networks.However, regardless of the many security approaches and trust metrics available, trust-based routing still faces some security challenges, especially with respect to privacy. In this paper, we propose a novel trust-based routing protocol based on a fully homomorphic encryption scheme. The new protocol allows nodes, which collaborate in a dynamic environment, to evaluate their knowledge on the trustworthiness of specific routes and securely share this knowledge.
