Efficient Auditing Scheme for Secure Data Storage in Fog

As the Internet of Things (IoT) has in practically no time filled in ubiquity, haze to-distributed computing has arisen as a state-of-the-art new technique. Fog-to-cloud computing, in contrast to regular cloud computing, requires the involvement of additional entities outside the cloud service provider (CSP), such as mobile sinks and fog nodes. Because of these distinctions, fog-to-cloud storage's integrity auditing will be unlike that of conventional cloud storage. Tian et al. have recently taken the initiative to construct a public auditing system for cloud computing transition. Bilinear mapping, proof of knowledge, and other complex public key cryptography techniques are central to their strategy. It becomes utterly ineffective. In this research, we use the common private key cryptography methods of MAC and HMAC to create a more flexible and effective auditing system. Our auditing method is made solid via the use of MAC and HMAC. Finally, both theoretical research and experimental findings confirm that our suggested method is more cost-effective in terms of both data transmission and processing.
