摘要：Security of data is a big concern to individuals and organizations that may be compelled to use the cloud services since some of these data are quite sensitive. The major challenges that any Cloud Computing Service Provider (CSP) must overcome are to make sure that its servers (VMs) are free from hacking by masqueraders or other attackers inside the CSPs. Therefore, there is the need for data to be encrypted and then sent to the cloud. This will ensure that users/clients sensitive data-in-transit and at rest is protected. In our new cloud framework, we implement for the user the best-fit hybrid algorithm for their data combined with an enhanced security for the VM instance. We propose the use of hybrid algorithms for VMs and user data encryption. The algorithms include RSA, AES 256-bit, ECC and SHA-256 which makes up a strong framework for speed, security, and integrity mainly for individual users. In the case of bulk data or organizations, we propose Homomorphic Encryption where the provider can operate on the data without decrypting it. We minimize the indices for fast decryption and then the decryption algorithm will require the computation of only two pairing operations, the hybrid of the standard encryption techniques and the homomorphic encryption.
