Minimizing the security risks in hybrid cloud networks with the aid of optimal triple data encryption standard algorithm

Abstract

Security is one of the challenging problems in the hybrid cloud, because of the combination of private and public cloud. A novel algorithm has been presented in this paper, to secure the hybrid cloud networks during information storage and recovery. The algorithm consists of four modules: (i) data collection module, (ii) data de-duplication module, (iii) encrypted de-duplication module and (iv) user interface module. Initially, the document is collected using the data collection module and duplicate data is removed using the matching score mechanism. This de-duplicated data is encrypted using the Optimal Triple Data Encryption Standard (OTDES). To enhance the performance of TDES, oppositional monarch butterfly optimization algorithm (OMBOA) is used in hybrid combination with TDES and this is referred as OTDES. This encrypted data is then stored on the cloud. The stored information can be accessed through the user interface module. Performance evaluation of the proposed security system has been carried out on the basis of different evaluation metrics and have been found in good order.
