Improved key generation scheme of RSA (IKGSR) algorithm based on offline storage for cloud

Abstract

Cloud computing is the most prominently used technology to store and recover information from anyplace with the assistance of web. One of the challenging tasks is to provide security to client information stored in cloud. To enhance the security of clients information, in this paper, (IKGSR) an improved key generation scheme for RSA algorithm is introduced which employs four giant prime numbers to create encoding (E) and decoding (D) keys. A database schema is also designed to save the key elements of RSA before it initiates.
