SecDSIM: A Framework for Secure Data Storage and Identity Management in the Cloud

Abstract

Cloud storage is a model of networked online storage where data are stored in virtualized pools of storage devices. Cloud storage requires users to host their data on the servers of cloud service providers. This raises issues of confidentiality, integrity, and availability of the data stored in the cloud environment. In this chapter, we propose a framework for secure data storage and identity management (SecDSIM) that can store data securely in the servers of cloud service providers using multi-user searchable encryption technique. The framework supports the process of verifying proof of storage correctness of the data by retrieving data identifiers any time around the cloud. The framework also supports dynamic updates for the encrypted data and indexes stored in the servers of cloud service providers.
