Dynamic Data Slicing in Multi Cloud Storage Using Cryptographic Technique

Abstract

In the modern era of computing, secure data sharing has become one of the challenges when considering the adoption of multi-cloud storage services. It has become one of the essential services in cloud computing. Many advantages of multi-cloud storage attracts the individuals and organization to move their data from remote to cloud servers. Recently many Multi-cloud storage services have been proposed but most of them focus on the single specific organization and file formats. In addition most providers use attribute based encryption which encrypts only particular database fields which reduces the trust of the many individuals and organizations. The biggest challenge that the present business world faces in multi-cloud storage is that there is no single standard architecture and procedure that can meet the requirements of the individuals and organizations. In order to address this challenge, this paper presents an effective architectural framework with a standard algorithm which would enable to enhance the secure data sharing through dynamic index based cryptographic data slicing. The proposed model is suitable for decision making process for the individuals and organizations in the adoption of multi-cloud storage service based on trust.
