A Unique Approach to Element Management and Secure Cloud Storage Backup for Sensitive Data

In this paper, the EMS is provided as a service to different sites of the organization using a private cloud. Sensitive data is stored in the public cloud which comprises of the current configuration of the complete private cloud, important disaster recovery data and management data. This would provide a confidential and secure backup of EMS. This would be useful in the case of natural calamities (tsunami, tornado, earth quake, etc.), terrorist attacks and any other disaster that strikes the private cloud. The clients/data owners, who require management data, can access the data from the public cloud. While accessing data from the public cloud, integrity and confidentiality of the data is preserved by using 2 techniques, namely Attribute Based Encryption (ABE) and Proxy Re-Encryption (PRE).
