Practical Attribute-based Multi-Keyword Ranked Search Scheme in Cloud Computing
TL;DR: This article introduces a semi-trusted server and builds a dual server model and is the first to put forward an attribute-based multi-keyword ranked search scheme against inside keyword guessing attack (ABKRS-KGA) to solve the mentioned two problems simultaneously.

Generic Construction of Outsourced Attribute-Based Encryption Without Key Escrow
TL;DR: This paper introduces a semi-trusted organization called ministrant attribute authority (MAA), and builds a key issuing protocol where AA and MAA not only cooperate with but also restrain each other skillfully to generate users’ secret keys.

An Anonymous Authentication Protocol Based on Cloud for Telemedical Systems
TL;DR: A promising solution satisfying the requirements of cloud computing scenarios for telemedical systems that could provide both data confidentiality and message authenticity while preserving anonymity is proposed.
Practical Attribute-Based Conjunctive Keyword Search Scheme
TL;DR: This paper designs an efficient method to combine the keyword search process in ABKS with inner product encryption and deploy several proposed techniques to ensure the flexibility of retrieval mode, the security and efficiency of the scheme.
