A Security Architecture of Cloud Computing for Business applications

Abstract: Cloud computing is internet based computing in which it provides on demand access of resources and services at lower cost. It is very necessary to consider security, privacy and integrity when designing and using cloud services because both user data and programs are resides in the cloud service provider premises. Integrity checking becomes imperative to secure data in a cloud environment. It is important to ensure that the stored data is neither compromised nor corrupted. Many of existing protocols reveals client’s sensitive data by sharing the encryption and decryption keys with the cloud server. The proposed work draws conceptual cloud architecture by adopting a hybrid encryption/decryption system algorithm to ensure the security and doesn’t compromise any information with the cloud server. It involves a third party called privacy manager who encrypts the clients’ information for ensuring the security. It then generate the hash value of the encrypted data, store and manage these details for verification purpose. This paper provides data integrity and user privacy through Privacy Manager
