Security in Searching Shared and Encrypted Data

Abstract: When private data content is stored in databases that are under the control of others, a formal way to protect the data, is to encrypt the data before storing in the database. To retrieve the data efficiently, a search mechanism is needed that works over the encrypted data an encryption scheme where each authorized user in the system has user own private keys to encrypt and decrypt data. The method supports keyword search which enables the server to return only the encrypted data that satisfies an encrypted query with decrypting itat client side. For strong authentication we are implementing the AES 128 with 16 bit algorithm is implemented. We can deploy this system on the cloud server.

Keywords: Encrypted Data, private data, retrieve, database.
