摘　　要：在介绍著名的孙子定理和欧拉函数的基础上,提出了一种新的口令验证方案。介绍了他的数学基础、原理和具体实现过程,进行了方案安全性和可操作性的分析。该方案简便、实用、存储量小、保密性和可操作性较强,克服了以往诸如基于拉格朗日多项式的口令验证方案等方案的缺点,适应于当今系统网络成员不断变化的情况,具有一定的理论和实践意义。A new password authentication scheme is proposed after introducing the famous Sunzi theorem and Euler function. Then introduction is made in mathematics basics and scheme authentication process. Finally analysis is made on the scheme security and feasibility. The scheme with its advantages such as high feasibility, security and low storage cost overcomes the defects in other authentications such as the password authentication scheme based on the Lagarange polynomial. It is meaningful in theory and practice for the changeable network of nowadays.
