Secure Cloud DBaaS by Client and Server side Encryption

Storing confidential data in cloud must provide guarantee of security and availability of the data, even though many alternatives are existed for handling and storing of data, while information confidentiality solution for the dbase are still unfinished. The new architecture that integrate cloud storage service with data privacy and possess a feature of executing concurrent operations on encrypted data and along with the geographically distributed clients to connect directly to these cloud database which is encrypted and they also provided to execute their operations over the cloud database. This architecture eliminates the brokers (Intermediate proxies) it limits the scalability, elasticity, availability. High sensitive data are encrypted by RSA encryption and regular data are encrypted using AES technique so that overhead on the network can be minimized.
