ABKS-SKGA: Attribute-based keyword search secure against keyword guessing attack

open access: yesComputer Standards & Interfaces, 2021
Abstract In order to guarantee security and privacy of sensitive data, attribute-based keyword search (ABKS) enables data owners to upload their encrypted data to cloud servers, and authorizes intended data users to retrieve it. Meanwhile, ABKS outsources heavy search work to cloud servers, which makes ABKS adaptive to mobile computing environment ...
