Trusted Third Party Framework for Data Security in Cloud Computing Environment

Ravuri. Venkata Bhargavi, K. Narayana Rao

Abstract: Cloud computing paradigm enables the users to access the outsourced data from the cloud server without the hardware and software management. Some researchers have suggested that user data stored on a service-providers equipment must be encrypted [2]. Encrypting data prior to storage is a common method of data protection, and service providers may be able to build firewalls to ensure that the decryption keys associated with encrypted user data are not disclosed to outsiders. However, if the decryption key and the encrypted data are held by the same service provider, it raises the possibility that high-level administrators within the service provider would have access to both the decryption key and the encrypted data, thus presenting a risk for the unauthorized disclosure of the user data. we in this paper provides an unique business model of cryptography where crypto keys are distributed across the user and the trusted third party (TTP) with adoption of such a model mainly the CSP insider attack an form of misuse of valuable user data can be treated secured. Thus, the proposed method not only encrypts the sensitive data, but also detects the dishonest party to access the data using combined hash functions.
