基于合数剩余假设伪熵函数的优化
An Improvement of Pseudo-Entropy Functions Based on Composite Residuosity Assumption
-
摘要: 2011年Braverman等人在伪随机函数的概念上提出了自适应泄漏弹性的伪熵函数.针对该方案抗泄漏量一定的问题,文中对该方案进行改进,基于合数剩余假提出新的构建方案.从证明结果可以看出,新方案具有更高的抗泄漏量.Abstract: Braverman introduces pseudo-entropy functions based on pseudo-random functions in 2011.But the amount of leakage is not high enough, this paper we propose a new pseudo-entropy function based on composite residuosity assumption.From the proof, we can see that our new scheme can stand up more leakage.
