An Identity-Based Encryption Scheme for Data Security in Fog Computing

Fog computing provides better integration facilities between cloud computing and Internet of things with real-time interactions. It delivers faster computing functionalities sitting close to user applications and has local storage options. Despite these potentials in fogging, maintaining secure data communication is still a challenging issue and needs further development. In this paper, we have presented an Identity-Based Encryption (IBE) scheme that ensures secure data transmission to authorized users. To provide data security, we have proposed a four-level Hierarchical Identity-Based Architecture for Fog Computing(HIBAF). In addition, we have evaluated our scheme to analyze the performance in terms of user load, memory utilization, response time, and delay time over different sizes of datasets. Finally, we have compared our results with other cryptography systems to figure out the effectiveness of our scheme and found overall 30% efficient.
