Abstract

Recent technological advances such as the Internet of Things (IoT), fog computing, cloud applications lead to exponential growth in the amount of generated data. Indeed, cloud storage services have experienced unprecedented usage demand. The loss of user control over their cloud stored data introduced several security and privacy concerns. To address these concerns, cryptographic techniques are widely adopted at the user side. Attribute based cryptography is commonly used to provide encrypted and / or authenticated access to outsourced data in remote servers. However, the use of these cryptographic mechanisms often increase the storage and computation costs; consequently, the energy consumption in the entire cloud ecosystem. In this paper, we provide a comparative analysis of different attribute based cryptographic mechanisms suitable for cloud data sharing services. We also provide a detailed discussion of different reviewed schemes, w.r.t . supported features, namely security, privacy and functional requirements. In addition, we explore the limitations of existing attribute based cryptographic mechanisms and propose future research directions to better fit the growing needs of this cloud environment in terms of energy - savings, processing and storage efficiency and availability requirements.
