【摘要】 为解决数据共享下隐私保护的问题，设计了一种基于弹性秘密共享的多方部分洗牌协议。针对现有研究效率低下及应用性不足等问题，将弹性秘密共享与洗牌协议相结合以增强协议的容错能力和抵抗合谋攻击的能力；同时设计了一种具备较高的效率和良好的适用性的部分洗牌协议。通过对该协议的正确性、安全性分析以及与现有文献的对比分析，该协议在满足安全性的前提下，展现出较优的运算效率和较低的资源消耗，为协议的推广应用提供了可行的途径。更多还原

【Abstract】 To solve the problem of privacy protection in data sharing, a multi-party partial shuffling protocol based on elastic secret sharing was designed. Aiming at the problems of high inefficiency and insufficient application in the existing research, a method of integrating elastic secret sharing into the shuffling protocol was proposed, which improves the fault tolerance and anticollusion aggression of the protocol. Simultaneously, a partial shuffle protocol characterized by high efficiency and strong applicability was designed. Through the correctness and security analysis of the protocol, along with comparative evaluations against existing literature, the proposed protocol demonstrates superior computational efficiency and lower resource consumption while meeting security requirements, providing a viable pathway for its broader application.更多还原
