摘要：Nowadays Data sharing, maintenance, its security are major challenges in global world. User in the data sharing system upload their file with the encryption using private key. This property is especially important to any large scale data sharing system, as any user leak the key information then it will become difficult for the data owner to maintain security of the information. In this system provide a concrete and efficient instantiate of scheme, prove its security and provide an implementation to show its practicality. There are lots of challenges for data owner to share their data on servers or cloud. There are different solutions to solve these problems. These techniques are very much critical to handle key shared by the data owner. This system will introduce how to reduce burden of data owner, authenticate those who have the access to the data on cloud. SHA algorithm is used by the TTP to generate the key and that key will get share to user as well as the owner. The TTP module receives encrypted file F using AES Algorithm from the data owner and computes hash value using MD5 algorithm. It stores key in its database which will be used during the dynamic operations and to determine the cheating party in the system (CSP or Owner). Trusted Third Party sends file to Cloud Service Provider to store data on cloud.
