An efficient cryptanalysis scheme for secure data storage system in cloud using optimal dual encryption algorithm

Cloud computing gives adaptable infrastructure and high storage capacity for Big Data applications. Many of the cloud clients have been migrating or building their business into the cloud. However, various potential clients are as yet reluctant to take advantage of the cloud due to security and privacy concerns. Mainly, the proposed system consists of three modules such as: i) cryptographic security system (CSS) using dual encryption algorithm; ii) security blocking system using optimal double attack; and iii) generating optimal security system. At first, we design the security system using hybridisation of blowfish and data encryption standard (DES). From this, we evaluate how much amount of original information retrieved. Then, finally, to increase the security system, we design an optimal dual encryption based security system. At last, the quality of the work compared to other encryption techniques with minimum encryption time.
