Lightweight Ring Signatures for Decentralized Privacy-preserving Transactions

Lukas Malina, Jan Hajny, Petr Dzurenda, Sara Ricci

Abstract

Current digital transactions such as e-payments and e-voting services, should be secure and also offer privacy protection to their users in order to be widely used. This work focuses on advanced cryptographic solutions based on ring signatures that provide anonymity to payment senders or to voters during e-voting. Since more and more constrained mobile devices are used in current networks, the proposed technologies and solutions should be also efficient and provide reasonable computational complexity. In this paper, we present a lightweight privacy-preserving ring signature scheme that is suitable for anonymous transactions and e-voting services run in an environment with constrained devices such as handheld devices and IoT nodes. Our solution provides the fast verification of signatures without using heavy operations such as pairings and exponentiation. Further, we add signature linkability and uniqueness in order to provide double-spending protection.
