Using Advance Encryption Standard Algorithm to Secure Cloud Data at Client Side Independent of Cloud Providers

Abstract

Cloud computing brings a lot of advantages especially in ubiquitous services where everyone can access computer services through the internet. In spite of this, there are key security loop holes that is making users anxious about the safety of migrating to the cloud. This project uses the Advance Standard Encryption Standard Algorithm to encrypt user data at client side before transferring the data to the cloud thereby making encryption key available to only owners of the data. The project also uses Message Digest Algorithm to check for data integrity at client side to know if client’s data has been tempered. The project also employs key management technique and backup design to keep encryption keys safe at client side.
