Cloud computing is playing a much important role in comparison to other fields of IT, in providing Data storage, Data security, Quality of Services (QoS) etc. Many data security factors have also increased due to the fast evolution of cloud in the IT industry. Therefore many security models and techniques have been deployed and are been in execution for providing more & more security to the data, especially the sensitive & private one. Despite of that much security, many of the models/techniques lacks in one or more security threat measures. In this paper a new model have been proposed & designed which comprises of two techniques in parallel. This model adapts Homomorphic Encryption scheme for the encryption of data at the client side and SSL-128 in parallel as a secure tunnel for all the transmission and communication from the user to the cloud and vice versa. The data file being sent to the cloud vendor for storage will comprise of data’s context and decryption keys, both of which will be encrypted separately with the same encryption algorithm. When retrieving this file, user will send query consisting of user’s data request & decryption key values. Decryption key values will be separated by query engine and will be saved in Decrypter for decrypting the Encrypted Decryption keys attached with the data. These decryption keys, attached with data, will be decrypting the data’s context when received at user’s end through the Decryption Algorithm Component.
