Abstract: Secure multi-party computation is an important branch in the modern cryptography field and also an important explored subject in the information security field.Based on secure multi-party computation protocol,for one thing it can realize the intercommunication and cooperation in internet and the other it can ensure the information secret.In recent,many scholars design some basic protocols under the semi-honesty model,but lack of the research about the protocol of hostility model.The paper introduces several division-related protocol and concrete secure two-party protocols based on the semi-honesty and hostility model.

Key words: secure multi-party computation, protocol, oblivious transfer 1 out of p protocol, semi-honesty model, hostility model

摘要: 安全多方计算是现代密码学领域中一个非常重要的分支,也是信息安全方向一个重要的研究内容。利用安全多方计算协议,一方面可以充分实现网上的互连合作,另一方面又可保证秘密的安全性。近年来,很多学者在半诚实模型下给设计出了一些基础协议,但关于恶意模型的协议的研究相对较少,给出了有关除法的几个协议,并分别对半诚实模型和恶意模型都给出了具体的安全双方计算协议。
