A Study of User Authentication Techniques in Cloud Computing

Major challenges in cloud computing are security and privacy because of its multi-tenancy nature and the subcontracting of infrastructures. Enterprises, government organizations and educational institutions are quickly accepting cloud services for their businesses. Cloud events need to be developed so that these organizations can be assured of security in their businesses and can choose an appropriate vendor for their computing needs. Various malicious activities from illegal users such as data misuse, strict access control and limited checking may result into harmful or illegal access of critical and private data of these cloud users. In this work, the researchers present a brief view of user authentication techniques in cloud computing environment.
