SeDaSC: Secure Data Sharing in Clouds

                 Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a public utility. [Source - wikipedia].
However, cloud storage gives rise to security concerns. In case of group-shared data, the data face both cloud-specific and conventional insider threats. Secure data sharing among a group that counters insider threats of legitimate yet malicious users is an important research issue.
                 An IEEE paper for handling this problem has been published - SeDaSC: Secure Data Sharing in Clouds. We will be following this paper and will be implementing this for overcoming the above security issue. We are implementing a secure data sharing enviornment which provides
  • data confidentiality and integrity
  • access control
  • data sharing (forwarding) without using compute-intensive reencryption;
  • insider threat security
  • forward and backward access control
