Comparative Analysis of Cryptographic Algorithms for Data Security in Cloud Computing: A Performance Evaluation

In the modern era, people are sharing their data online. securing this data in today's world is a crucial task i.e., anyone can get the data without the concern of the respective authority. Users store their sensitive/non-sensitive data on the cloud only by trusting the Terms & Conditions and the user agreement offered by the service provider. Cloud service providers are known to reject the responsibility for any data breaches that may happen. This paper proposes a method to strengthen the confidentiality of data in cloud. We have done comparative study between several cryptographic algorithms on the basis of their encryption and decryption time, performing ondifferent data formats like text, image, and videos.
