Abstract

The advancement of technology rises many of new area of computer technology, cloud computing is one of them. It is a new conceptual based service that use by many small and big organization. In a cloud computing data may be stored at varied locations, both physically and geographically.Therefore in order to resolve the issues in cryptographic security a new methodology is required to develop. That provides the data security based on DNA cryptography for cloud data storage.In this paper, we proposed cryptography based mutual authentication system for data security. We implement DNA algorithm using AES encryption and decryption. Our experimental results demonstrate the effectiveness and efficiency of our technique when evaluating user authentication.

Introduction

Cloud computing is an emerging technology which recently has drawn significant attention from both industry and academia. Cloud computing provides a centralized pool of configurable computing resources and computing outsourcing mechanisms that enable different computing services to different people to their perspective. Cloud storage is a networked model of enterprise storage where data is stored in virtualized storage pools which are generally hosted by third parties. Cloud service hosting companies operate large data centers and people who require data to be hosted, buy or lease storage capacity. The data center operators, provides the resources based on the requirements of the customer and expose them as available storage, which the customers can use to store files or data objects. Actually resource may span across multiple servers and multiple locations. Safety of the files depends upon the hosting companies and on the applications that leverage the cloud storage [1] [2].In this research work we demonstrate the security for cloud data security with client server mutual authentication. Therefore need to develop a secure model which aims to find a secure and efficient manner for data storage and access for the cloud data centers. Therefore the work is intended to explore the security techniques over cloud, more specifically in terms of cryptographic solutions. 1. Cloud Computing Cloud computing now is everywhere. In many cases, users are using the cloud without knowing they are using it. According to [3], small and medium organizations will move to cloud computing because it will support fast access to their application and reduce the cost of infrastructure. The Cloud computing is not only a technical solution but also a business model that computing power can be sold and rented. Cloud computing is focused on delivering services. Cloud computing is a computing paradigm, where a big pool of systems are associated in confidential or public networks, to provide dynamically scalable infrastructure for purpose, data and file storage. With the arrival of this technology, the cost of computation, application hosting, content storage and release is reduced considerably. Cloud computing is a practical approach to experience direct cost remuneration and it has the impending to convert a data center from a capitalintensive set up to a variable priced environment. The idea of cloud computing is based on a very primary major of, reusability of IT capabilities'. The difference that cloud computing carry compared to conventional concepts of “grid computing”, “distributed computing”, “utility computing”, or “autonomic computing” is to widen horizon across governmental boundaries. Forrester defines cloud computing as

Conclusion

Privacy and security in cloud can be said to be achieved when users have control over information they want to reveal to cloud and who can access their information. Without guarantee of security and privacy users can\'t make shift to cloud only on the basis of lower cost and faster computing. The cloud computing is respectively new domain of research and development. A number of new directions are appeared due to introduction of this technology. In this presented work the cryptographic cloud and their security issues are investigated. In this context the available cryptographic solutions are not suitable due to higher computational overhead and the storage overheads. Therefore a new kind of cryptographic approach is required to minimize the computational cost as well storage of cryptographic data. Therefore in order to resolve the addressed issue a new DNA computing for client server mutual authentication of data storage is proposed. The proposed security architecture is an enhance hybrid security architecture which is designed through DNA based cryptographic approach and an authentication server implementation. This technique is used for AES for encryption and decryption of data file. On the other hand, a look up table is generated of DNA using MD5 hash generation. The developed system follows an OTP (one time password scheme) for authenticating the users by sending the mail on authenticate user ID. Therefore, the proposed model enhances the security over the cloud data of client mutual authentication
