Secure cloud storage based on cryptographic techniques
Cloud computing is the delivery of computing and storage capacity as a service to users.Cloud storage,as a subservice of infrastructure as a service (IaaS) in cloud computing,is a model of networked online storage where data is stored in virtualized pools of storage.As fast development and application of cloud computing and cloud storage,users concern more and more about security and privacy issues involved in these techniques.From industrial and academic viewpoints currently,cryptography is considered as a key technology to solve security and privacy problems.In this paper,we mainly give a review on research results of secure cloud storage in which cryptographic techniques have been used to their designs.We start form reviewing the definition of cloud storage,and subsequently review the existing secure cloud storage based on cryptographic techniques.Moreover,we analyze and indicate what type of cryptographic techniques is mainly adopted in existing cloud storages and what role the cryptographic techniques play.Through this work,we can better catch what the relationship between secure cloud storage and cryptographic techniques,and how about the application mechanism of cryptographic techniques in cloud storage.We hope this review can give some help for future research,and more secure cloud storages by using cryptographic techniques can be proposed in the future.
