函数加密综述

A survey on Functional Encryption

Carla Mascia, Massimiliano Sala, Irene Villa

摘要:

功能加密(FE)以两种不同的方式扩展了传统的公钥加密:它支持细粒度的访问控制,并允许学习加密数据的函数。在本文中,我们回顾了所有FE类,描述了它们的功能和主要特点。特别是,我们提到几个计划,为每个类,提供他们的安全性假设和比较他们的属性。据我们所知,这是第一次涵盖整个FE系列的调查。

英文摘要:

Functional Encryption (FE) expands traditional public-key encryption in two different ways: it supports fine-grained access control and allows learning a function of the encrypted data. In this paper, we review all FE classes, describing their functionalities and main characteristics. In particular, we mention several schemes for each class, providing their security assumptions and comparing their properties. To our knowledge, this is the first survey that encompasses the entire FE family.
