Secret sharing based on quantum Fourier transform

Secret sharing based on quantum Fourier transform Secret sharing plays a fundamental role in both secure multi-party computation and modern cryptography.

Abstract

Secret sharing plays a fundamental role in both secure multi-party computation and modern cryptography. We present a new quantum secret sharing scheme based on quantum Fourier transform. This scheme enjoys the property that each share of a secret is disguised with true randomness, rather than classical pseudorandomness. Moreover, under the only assumption that a top priority for all participants (secret sharers and recovers) is to obtain the right result, our scheme is able to achieve provable security against a computationally unbounded attacker.
