Abstract

Internet of Things (IoT) enables devices to get connected to the internet. Once they are connected, they behave as smart devices thereby releasing sensitive data periodically. There is a necessity to preserve the confidentiality and integrity of this data during transmission in public communication channels and also permitting only legitimate users to access their data A key challenge of smart networks is to establish a secure end-to-end data communication architecture by addressing the security vulnerabilities of data users and smart devices. The objective of this research work is to create a framework encompassing Ciphertext policy Attribute-based Encryption scheme using block encryption and BLAKE hashing technique. An improved Pairing-Free-Ciphertext policy Attribute-based encryption algorithm has been developed to overcome the aforementioned challenges. Further, a comparative study has been performed between the proposed scheme and the different encryption algorithms. It is found that the proposed scheme scores well over the already existing schemes. The scheme is evaluated in terms of execution time and communication overhead. The robustness of the proposed scheme is also analyzed from the perspective of several security goals.
