针对当前互联网上流行的逢低买入拍卖机制,利用分布式ElGamal加密方案的同态引理在半诚实模型下设计了一个不使用拍卖行的拍卖协议,使买家在不泄露各自信息的情况下共同计算出成交价,并对协议的正确性和安全性进行了分析,然后对该协议进行了一般化推广,提出了一个安全多方计算中的基本问题——安全区间分布问题,给出了该问题的通用解决方案,并探讨了该方案在实际中的应用.
Aiming at the current bargain-hunting auction mechanism on the internet, a homomorphic lemma of distributed ElGamal encryption scheme is used to design an auction agreement without semi-honest model under the semi-honesty model so that buyers can not disclose their own information And then calculate the transaction price together, and analyze the correctness and safety of the protocol. Then generalize the protocol and put forward the basic problem of secure multi-party calculation-the distribution of safety intervals, The general solution to the problem, and discusses the practical application of the program.
