HYBRIDIZATION OF RSA AND BLOWFISH CRYPTOGRAPHY ALGORITHMS FOR DATA SECURITY ON CLOUD STORAGE

Security is provided for data according to the requirements of client. Cloud computing provides different types of services. Apart from the advantages of cloud, it has many security related issues. The topmost challenge in cloud is data security. There are more possibilities that the data are accessed by the other users of cloud storage. Data security must be addressed in the cloud storage. Cryptography is the most known technique for securing the data by encryption. It is necessary to propose encryption techniques which are suitable for cloud storage. Every cloud computing provides the different level of security. The aim of this study is to improve on the security of data or file stored on cloud storage using hybrid cryptographic algorithms for encryption. The algorithms are designed in such a way that one authenticates the authorized user and the other provides confidentiality and security for data stored on cloud.
