| 摘 要： | 在对原MFE加密方案进行了分析，它不能抵抗SOLE攻击；在原有基础上改进了原方案的中心映射，改进的方案使攻击者不能得到相关的线性化方程，从而抵抗SOLE攻击；分析表明新方案不仅能够抵御SOLE攻击，而且能抵御秩攻击和Grobner攻击，是一种更为安全的多变量公钥加密方案。

| Abstract: | This paper analyzes original Medium-Field Encryption （MFE） scheme because it can not resist SOLE attack and improves the central mapping of the original scheme based on original MFE.The revamped scheme makes the attacker not obtain the related linearized equation so that the revamped scheme can resist SOLE attack Analysis shows that the new scheme, which can not only resist SOLE attack, but also resist rank attack and Grobner attack, is a kind of more secure muhivariable public key encryption scheme. |
