可搜索加密研究综述

A Review of Searchable Encryption Research

为了有效解决数据隐私保护和安全搜索等问题,可搜索加密技术应时而生。可搜索加密是一种保护数据隐私的加密技术,允许在加密的状态下进行搜索和查询。可搜索加密的研究主要包括对称可搜索加密和非对称可搜索加密等,其基本原理包括对关键词进行编码和加密,设计相应的索引结构和搜索算法。可搜索加密技术在云计算、医疗健康、金融和物联网等领域具有广泛的应用潜力。研究者致力于提供效率更高、安全性更好、扩展性更强的可搜索加密方案。介绍了可搜索加密的相关研究历史以及2种可搜索加密技术,从安全性和关键词猜测攻击分析了可搜索加密技术的实用性,还指出了该领域存在的亟需解决的问题和今后的研究方向,在推进可搜索加密的进一步研究方面发挥了作用。

In order to effectively solve the problems such as data privacy protection and secure search,searchable encryption technology has emerged.Searchable encryption is an encryption technique that protects data privacy and allows search and query in an encrypted state.The research on searchable encryption mainly includes symmetric searchable encryption and asymmetric searchable encryption,etc.Its basic principles include encoding and encrypting keywords,designing corresponding index structures and search algorithms.Searchable encryption technology has a wide range of potential applications in cloud computing,healthcare,finance,and the Internet of Things.Researchers are committed to providing searchable encryption schemes that are more efficient,secure,and scalable.The history of research on searchable encryption and two kinds of searchable encryption technologies are introduced,and the practicability of searchable encryption technologies is analyzed from the perspectives of security and keyword guessing attacks.The urgent problems that need to be solved in this field and the future research directions are also pointed out.These works have played a role in promoting further research on searchable encryption.
