Keyless Fuzzy Search for Data-based Access Control

Presentation By: Tianxin Tang
ABSTRACT | Key management is always problematic in terms of privacy for remotely stored data in a decentralized environment. To alleviate this issue, we propose a concept called "keyless fuzzy search," where users can query an encrypted database, retrieve its parts and decrypt only if they possess
some information "close to" the encrypted data. While strong security in such a keyless setting is impossible to achieve, our approach prohibits remote encrypted data from being easily mass-harvested or mined, as guessing the right queries can be costly for attackers if the data has some entropy.
Tianxin Tang is a Ph.D. student in the School of Computer Science whose interests lie in cryptography. She is advised by Alexandra Boldyreva.
