A Survey of Security Research on Searchable Encryption
摘要
Abstract
Searchable encryption is a crucial technology addressing data security and privacy protection problems in cloud computing and big data environments.It enables users to securely search encrypted data without the need for decryption.Nevertheless,there has been an influx of re-search focused on attacking searchable encryption in recent years,which has undermined its secure search capability.To thoroughly comprehend the security of searchable encryption,this paper will review and delve into the advancements in security research related to searchable encryption.The study of searchable encryption is divided into public key encryption with keyword search(PKES)and symmetric searchable encryption(SSE).This paper begins by introducing the concept of public key searchable encryption,discussing the severe challenges faced by existing public key searchable encryption schemes,such as user privacy,keyword guessing attacks,and ciphertext keyword e-quality testing,and then provides specific solutions and methods.The paper further elaborates on the security model of symmetric searchable encryption,along with the attack and defense methods for symmetric searchable encryption schemes.Finally,it identifies some need-to-be solved problems in searchable encryption and outlines future development directions.关键词
