Title:
Blockchain-based Secure D2D localisation with adaptive precision
Authors: Gewu Bu, Bilel Zaghdoudi, Maria Potop-Butucaru, Serge Fdida
Abstract:In this paper we propose a secure best effort methodology for providing localisation information to devices in a heterogenous network where devices do not have access to GPS-like technology or heavy cryptographic infrastructure. Each device will compute its localisation with the highest possible accuracy based solely on the data provided by its neighboring anchors. The security of the localisation is guarantied by registering the localisation information on a distributed ledger via smart contracts. We prove the security of our solution under the adaptive chosen message attacks model. We furthermore evaluate the effectiveness of our solution by measuring the average register location time, failed requests, and total execution time using as DLT case study Hyperledger Besu with QBFT consensus.
