A Trusted Cryptography Key Framework for User Data Storage in Cloud Environment

Cloud Computing is a service based technology and, one of the service based cloud is Data Storage as a Service (DSaS), Cloud has been an readymade option for data storage, Basically an Cloud Service Provider (CSP) provides DSaS for the user, and user from anywhere can store their data on to the cloud by means internet connectivity. This transfer of data from user data origin to the cloud storage destination involves many security issues which has to be answered by the cloud provider, many researchers have proposed valuable research but still an economical and business model has to be searched, we proposed an ECC based PKI certificate framework. ECC based PKI has advantages over tradition RSA based PKI along cost of computation, key size, transmission overhead. We have designed Secured Cloud Storage Framework (SCSF). In this framework, users not only can securely store and access data in cloud but also can share data with multiple users through the unsecured internet in a secured way. This scheme can ensure the security and privacy of the data in the cloud.
