ABSTRACT

Cloud computing is an Internet based technology where a large amount of computing resources are shared as a services. Since data is shared in cloud, security of the data is considered as the major concern in cloud computing. However, privacy and security is the trending topic in cloud computing technology, which leads to the abundant research in that area. In this study the proposed multi-level algorithm that will enhance the data security in cloud computing was designed by combining the multi-prime RSA and MD5 algorithms which will provide integrity and confidentiality of data in cloud computing. In the algorithm, the multi-prime RSA used for encrypting data and the MD5 used to provide a message digest and a digital signature at the same time. The designed algorithm is implemented using a java netbeans environment and we found out that, the algorithm is resistance to attacks such as mathematical attacks, brute force attacks and a hacker cannot separate the signature and the original message.
