COBBS: A Multicloud Architecture for better business solutions

Abstract

Adapting to the latest technological advancement is the only means for sustainability and growth for any organization in this era of fast growing business world. Cloud computing have proved to be a great boon for business development as it provides servers across the globe for storing data securely and performing computations on them. However security challenges still pose a great threat for using clouds especially in handling sensitive data. This paper throws light into different existing Multicloud approaches and then proposes a novel architecture named COBBS. Partitioning data and logic part of an application and performing a strong encryption scheme like homomorphic encryption before storing in cloud is the base of COBBS. Homomorphic encryption is different from other encryption schemes as it can perform computations on encrypted data, excluding the need for sharing a secret key and preventing the exposure of most valuable data even from the cloud service providers.
