Enhancing Data Security in Cloud Computing Using RSA Encryption and MD5 Algorithm

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.
