Paper Title
Secret Sharing in Multi-Clouds

Abstract
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.
