Abstract
Cloud has become very important in internet world. Cloud provides storages, platforms which improves the functionality. Cloud storage shows how securely and flexibly we can store and share our data. This technique introduces a special type of encryption called as key-aggregate cryptosystem which allows user to share their data partially across cloud and which produces constant size ciphertext. In this technique user provide a constant-size aggregate key for different ciphertext classes in cloud storage, but the other encrypted files outside the class remain confidential. We also compare this technique with existing one. We implemented this cryptosystem for public-key patient-controlled encryption system.
