Cryptanalysis of Keyword Confidentiality in a Searchable Public-Key Encryption Scheme Against Malicious Server

open access: yesIET Information Security
Public-key authenticated encryption with keyword search (PAEKS) is a novel cryptographic primitive to resist against keyword-guessing attacks (KGAs) and preserve the privacy of keywords in both ciphertexts and trapdoors.

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 ...
