摘要

Garg, Gentry和Halevi (GGH)描述了第一个使用理想格的候选多线性映射。然而，胡和贾在GGH地图上提出了一种有效的攻击方法，打破了基于GGH的MPKE。我们描述了一种改进的GGH地图。我们的结构的安全性取决于新的硬度假设。

Improvement of GGH Multilinear Map

Garg, Gentry and Halevi (GGH) described the first candidate multilinear maps using ideal lattices. However, Hu and Jia presented an efficient attack on the GGH map, which breaks GGH-based MPKE. We describe an improvement of GGH map. The security of our construction depends upon new hardness assumption.
