摘要/Abstract

摘要： 以实系数一元二次方程为研究对象，给出针对非线性方程的安全计算协议。在半诚实模型下，协议能够完成求解的计算任务，并且协议的正确性和保密性也得到了论述。在求解一元二次方程安全两方协议的基础上，对两种类型的二次方程组进行了研究，进一步给出相应情形下的安全两方计算协议。

关键词: 安全两方计算协议, 一元二次方程, 不经意传输OT^p₁协议

Abstract: The secure two-party computation problem of the quadratic equation in one unknown with real coefficients is studied， the protocol is proposed. In the semi-honest model， the protocol can complete the task satisfying privacy and correctness. Then protocols of two kind systems of nonlinear equations are given based on that one.

Key words: secure two-party computation protocol, quadratic equation with one unknown, oblivious transfer 1 out of p protocol
