A Dilithium-like Multisignature in Fully Split Ring and Quantum Random Oracle Model
Abstract
Multisignature schemes are crucial for secure operations in digital wallets and escrow services within smart contract platforms, particularly in the emerging post-quantum era. Existing post-quantum multisignature constructions either do not address the stringent requirements of the Quantum Random Oracle Model (QROM) or fail to achieve practical efficiency due to suboptimal parameter choices.
In this paper, we present a novel Dilithium-based multisignature scheme designed to be secure in the QROM and optimized for practical use. Our scheme operates over the polynomial ring
