A Secure Framework for User Data Storage in Public Cloud Systems using Symmetric Cryptography

Cloud computing is a paradigm shift over the Internet which provides instant access to software, hardware and computing information resources for use when they needed. Cloud Computing is the access of data, software applications and computer processing power through a “cloud” of online resources. Cloud computing involves storage of user data in the cloud. Cloud architectures will constitute cost efficient mechanism that will support the storage, transmission and processing of the user application contents. A user can access cloud service as a utility service. The diversity of the services delivered through the cloud and sharing the distributed resources via network in the open environment results in a challenge to ensure that only authorized users can gain access to it. Thus, there is a critical need to have a secure framework for ensuring confidentiality and integrity of stored data in cloud. To ensure the data security, we proposed a method for efficiently storing and data in a cloud infrastructure by building secure channels for data communication.
