Security enhancement for datamigration in the cloud

Abstract

In today's society, cloud computing has significantly impacted nearly every section of ourlives and business structures. Cloud computing is, without any doubt, one of the strategic directionsfor many companies and the most dominating infrastructure for enterprises as long as end users.Instead of buying IT equipment (hardware and/or software) and managing it themselves, manyorganizations today prefer to buy services from IT service providers. The number of service providersincrease dramatically and the cloud is becoming the tools of choice for more cloud storage services.However, as more personal information and data are moved to the cloud, into social media sites,DropBox, Baidu WangPan, etc., data security and privacy issues are questioned. Daily, academiaand industry seek to find an efficient way to secure data migration in the cloud. Various solutionapproaches and encryption techniques have been implemented. In this work, we will discusssome of these approaches and evaluate the popular ones in order to find the elements that affectsystem performance. Finally, we will propose a model that enhances data security and privacy bycombining Advanced Encryption Standard-256, Information Dispersal Algorithms and Secure HashAlgorithm-512. Our protocol achieves provable security assessments and fast execution times formedium thresholds.
