Abstract: Sharing data using cloud storage has become a prominent part of a lives therefore, it is necessary to be able to share data to the people we choose and which data we choose. In this article, Key Aggregate Cryptosystem scheme, a public key encryption scheme which produces fixed-size cipher texts [1], is studied comprehensively along with its application in sharing data by users across cloud platform. KAC provides efficient and flexible delegation of keys for sharing selective data using single aggregated key without compromising on other data stored in cloud. The scheme is implemented using python file integrated in the backend of a website, which is in Django and the cloud storage used is Amazon S3. The data is stored in buckets and can be accessed using the website. Users can also upload and download their data from the website, or even share after uploading on the cloud.
