Secret Sharing in Multi-Clouds

Single cloud has become very common in many organizations. The main reason for this popularity is the increase in productivity, cost efficiency, accessibility, and reliability. But now there is a movement towards a multi-cloud environment so that organizations can distribute the workload. This also eliminates the risk of service unavailability that customers often come across. Hence, lately, there has been a buzz around multi-clouds or inter-clouds or cloud-of-clouds. This paper focuses on maintaining the security in multi-cloud storage using a (􀢚, 􀢔)-threshold secret sharing mechanism. We also use multi-level threshold secret sharing using Chinese Remainder Theorem for hierarchical cloud infrastructure. Analysis of the security features proves that this scheme achieves data security. Index Terms - Chinese Remainder Theorem, Multi-Clouds, Security, Secret Sharing.
