Abstract

In these days, storing data over the cloud has become popular. Many organizations and companies have moved to the cloud and they are continuously benefiting from its rising usefulness and convenience. Before the cloud, saving documents or information was simple. All we had to do is save them on our computer or an external hard drive but the information could not be accessible from anywhere which was resolved by cloud storage. Every process has its own pros and cons. Similarly, storing data in the cloud has many pros but is not without cons. Data could still be accessed by cybercriminals using complicated approaches, even though storing data on cloud is safe. That is the reason why every person should be cautious of their own data or information; else their information could be in the hands of data stealers who might disclose the data, if best practices are not applied. In organizations, if employees are not taught or well-informed, data can accessed by attacker. Therefore, this paper discusses about making use of symmetric block cipher technique i.e., AES algorithm in the fog node for the data to be stored oncloud.
