隐私保护的匹配加密研究综述OA

Matchmaking encryption(ME),as an emerging branch of public key encryption,provides a novel approach for protecting data privacy.It allows a sender and a receiver possessing specific attributes,to specify access policies that the other party must satisfy.The ciphertext can only be decrypted correctly by the receiver if and only if both parties'attri-butes satisfy each other's access policies.Otherwise,nothing is revealed beyond the fact that the match fails.This encryp-tion model enables controlled message sharing between two parties,preserves the privacy of both the message content and the sender's access policies,and demonstrates broad application prospects.Beginning with the basic concepts of ME,this paper introduces related technologies and their latest developments both domestically and internationally.Finally,it sum-marizes the development trends and future research directions for ME.
