Comparison of Symmetric and Asymmetric Algorithms for Cloud Storage Security - Tamane, S.M.Chavan, Dr.S.C. (International Journal of Advanced Science and Technology, 2020)
Cloud computing security protects data access of unauthorized users and modification of information. Cloud security contains set of policies, different technologies and some control for data storage. Cloud server increases the availability of resources since anyone can access the data using web. To secure the data it is important to achieve confidentiality. If the data is encrypted and stored on cloud, it is difficult for unauthenticated users to retrieve data .This paper focuses on transmitted data security that should be maintained by different encryption and decryption methods. System uses cryptographic algorithms like RSA, AES and proposed algorithm. System shows comparison of symmetric and asymmetric algorithms for storing data on cloud server. Thus paper has designed a scheme to provide data confidentiality to store data on cloud. Transmitted data can be protected from passive attacks. Along with the cryptographic algorithms system uses packet analyzer, rule design, analysis of time comparison to encrypt data. onedrive cloud is used for storage purpose.
