A (t, n) Threshold Quantum Secret Sharing Scheme with Fairness

摘要

Quantum secret sharing is an important technique of quantum cryptography. A (t, n) threshold quantum secret sharing scheme with fairness is proposed. Firstly, the proposed scheme only requires the distributor to provide a share for each participant to achieve fairness. Secondly, the distributor interacts with participants only during the secret distribution phase. Another important point is that our scheme combines the privacy features of secure multi-party computing to ensure the reuse of participants' secret shares. Finally, in our scheme, the correctness, security and fairness are discussed in detail.
