Secure Authentication and Key Management Protocol in Cloud Computing

Abstract

Cloud computing has brought revolution in IT (Information Technology) sector. It has transform the way organizations and individuals  process, store and access applications and data ,  by offering scalable and on-demand access to computing resources including networks, servers, storage  and applications.  It is a flexible service that  allows users to dynamically scale up and down  their resources based on demand which enhances  efficiency and optimizes resource utilization .Cloud computing offers number of benefits and saves cost. It  eliminates the need for investing  in hardware and software. Cloud computing allows users to work from anywhere over internet connection which enhances productivity .However, cloud computing has some challenges such as Security concerns that include unauthorized access and data breach. To provide security in cloud computing environment various authentication and authorization protocols exist but they also suffers from various security attacks. Nowadays three factor MAKA (Mutual Authentication and Key Management) protocol  has gained popularity but they also lacked as they don’t have dynamic revocation mechanism .To address these issues we have proposed a system  based on id , password and biometric based authentication that has  dynamic revocation mechanism and can resist various known attacks.
