文章主要介绍了Gentry突破性的工作:基于格的全同态加密方案的构建蓝本,对Gentry的构造思想、构造过程等方面进行了详细的描述。随后介绍了两种全同态加密方案的实现方法,详细介绍了两种方案的构造过程,并对其安全性和有效性进行了分析讨论。
The article mainly introduces Gentry’s groundbreaking work: the blueprint of the lattice-based all homomorphic encryption scheme, and the detailed description of Gentry’s construction thought and construction process. Then introduced the realization methods of two kinds of isomorphic encryption schemes, introduced the construction process of the two schemes in detail, and analyzed the security and validity of the two schemes.
