Energy Preserving ABE-Based Data Security Scheme for Fog Computing

Abstract

A cutting-edge technology called fog computing makes it possible to offer services and applications for IoT/end devices at the network's edge quickly and effectively. As the fog computing paradigm is driven from the cloud computing paradigm, the security and privacy concerns have been also passed down to fog. But fog and cloud differ in terms of architecture and capabilities, thus the available cloud solutions are irrelevant to the fog. Moreover, fog is resource constrained in nature as well as it has limited energy as it runs over batteries. Therefore there is a need to develop an energy preserving lightweight security scheme to secure the data as well as to provide a fine grained access control mechanism. Thus, in this article we have developed a cryptosystem based on Chosen-Ciphertext Attribute-based encryption (ABE) with dynamic key change in order to secure the data and to prohibit unauthorized access in an energy efficient manner. We have evaluated and analyzed the sturdiness and the security of our proposed cryptosystem considering the energy consumption and mitigating attacks as primary aspects. Additionally, our cryptosystem is effective and energy efficient compared to other techniques.
