Cloud computing has revolutionized how services are rendered and used by some many people in the world like providing hardware, software and infrastructural storage to many users at any time. This is in terms of software as a service, platform as a service and infrastructure as a service, hence providing room for convinience to the cloud consumers to choose what they want presently and catering for their future needs since its elastic. With the company's or individual's data held by a third party that is the cloud provider, it brings out the security issues in respose to confidentiality, availability and integrity of the data at the cloud provider's side. In this reseach paper solution is provided to maintain confidentiality of data and integrity of data at the cloud provider's side. This framework contains RSA encryption standard and MD5 hashing alogorithm. In this solution data is encrypted using RSA which generates both public and private keys used in the encryption and the decryption then using MD5 to generate the hash value which is stored before the data is sent to the cloud provider. The hash value is checked upon retriving of data from the cloud and if its still the same then the data was not modified or tempered with if else then the cloud provider has bleeched the contract. All these approaches undergo through the following steps Encryption, Hashing, Data uploading on a cloud, Verification and Decryption.

Eighth Sense Research Group
ABSTRACT Cloud computing is the technology through which people can share resources, services and information among the people through use of internet. Since we share the data through the internet, security is considered as a major issue. In Cloud computing several security issues arises like confidentiality, integrity and authentication. In this paper a new security model have been proposed. The architecture provides a mechanism through which we can get secure communication as well as hiding the information from unauthorized users. In this model we have implemented a combination of RSA encryption and digital signature technique which can easily with all types of cloud computing features like: PaaS, SaaS and IaaS. This combination mechanism provides three way security i.e. data security, authentication and verification. In this paper, we have proposed RSA encryption algorithm for confidentiality of data and for authentication MD 5 algorithm have been implemented. Keywords: - Cloud Computing, data security, MD5, RSA, encryption and digital signature.
Cloud Computing: Ensuring Data Storage Security in Cloud
International Journal of Engineering Development and Research, 2016
Cloud computing is a rising computing standard in which the computing framework is given as a service over the Internet. The Cloud computing tool gives facility of data storage and access for cloud users, but when outsourcing the data to a third party causes safety issue of cloud data so data are protected by restricting the data. We propose a new decentralized access control scheme for secure data storage in the clouds that supports anonymous authentication where identity of the user is protected from the cloud during authentication. The architecture is decentralized, meaning that there can be several KDCs for key management. Revoked users cannot access data after they have been revoked. The proposed scheme is resilient to replay attacks. In addition to this a new symmetric key cryptographic method called Modern encryption Standard (MES)-II presents method which can be effective to encrypt various types of plain text files and the method is free from standard cryptography attacks n...

Performance Analysis of Cloud Data Verification Using MD5 and ECDSA Method
2017
Cloud computing enable the users to outsource and access data economically using storage as a service. In this storage model, the data owner doesnot have any control of the data once its stores on cloud server. Therefore, privacy and security of the data is a challenging issue in cloud computing. To provide the integrity of the outsourced data, we have proposed a lightweight data auditing technique such as MD5 and ECDSA signature method using third party auditor. The result analysis of the proposed method shows that, ECDSA has better security performance than the computation as compared to MD5 method for larger data size. The selection of the signature method depends on the priority of the data size and frequency of accessing.

Cloud Computing is now a worldwide concept which is being utilized by majority of internet users. The number of institutions, companies and other personal users relying on the resources provided by the cloud and as well storing the critical information in the cloud has increased drastically over the years due to the simplistic and attractive features it possesses. One of the main challenging issues that needs to be tackled in the cloud computing is the security of data stored in the service providers' site. When storing data on cloud, one might want to make sure if the data is correctly stored and can be retrieved later. As the amount of data stored by the cloud for a client can be enormous, it is impractical OR might also be very costly to retrieve all the data, just to make sure that it is stored correctly. Hence there is a need to provide such guarantees to a client. Hence, it is very important for both the cloud provider and the user to have mutual trust such that the cloud provider can be assured that the user is not some malicious hacker and the user can be assured of data consistency, data storage and the instance he/she is running is not malicious. In this paper, thorough study and analysis is done on some of the research papers that has been written and published in this field. This paper presents literature survey on variety of approaches for implementing data security in cloud computing. The proposed system gives the concept of digital signature to maintain the trust worthiness. I.
