Distributed challenge response mechanism for error localization in cloud computing
V. Sree Ram,  K. senthil Kumar
Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications by using the concept of virtualization of resources. Though it provides various advantages, such a service also prone to several security issues as the data is outsourced, which leads to transparency of data, affecting the confidentiality. The outsourced data may be breached by unauthorized users who gain access to the data by breaching security levels of different servers where the information is stored. To provide security in this case encryption mechanisms are followed which reduces the dynamic data operations that can be applied over the encrypted data. To overcome this an approach which supports the use of homomorphic token generation and providing encryption at different stages of storing data in a remote system. And the auditing of data frequently for the purpose of integrity verification which can be achieved by validating the tokens generated along with the signature provided before outsourcing the data which helps in identifying the server which is being under attack or at risk.
