摘要
We construct the first secure multi-party quantum computation with public verifiable identifiable abort (MPQC-PVIA) protocol in the preprocessing model, which allows outside observers to agree on the identity of a malicious party in case of an abort. In order to achieve PVIA, we propose a new primitive called Auditable Quantum Authentication(AQA) that publicly identifies the malicious sender with noticeable probability. Our protocol is secure, assuming a post-quantum secure multi-party computation scheme with public verifiable identifiable abort.
