Research of quantum secure multi-party ranking protocol
Liu Wen, Yongbin Wang · Acta Physica Sinica · 2011
Secure multi-party ranking problem is used to rank n private integers without leaking further information. It is an extended problem of secure two-party comparing problem. A secure multi-party quantum ranking protocol in semi-honest model is presented based on the a quantum implicit module n+1 addition. The security for multi-parties of the protocol is analyzed.
