Development of Secure Multikeyword Retrieval Methodology for Encrypted Cloud Data

Cloud computing is a technology that uses the internet and central remote servers to maintain data and application. Concerns of sensitive information on cloud potentially cause privacy problems. So data encryption protects data security to some extent. For secure purpose of sensitive information on cloud, use vector space model and hybrid encryption algorithm (RSA and AES encryption-decryption) and OTP. Vector space model helps to provide sufficient search accuracy and the hybrid of RSA and AES algorithms for encryption of information. The OTP (One Time Password) for authentication. As a result, information leakage can be eliminated and data security is ensured.
