In recent years, due to the huge growth in using various services provided by the cloud computing, there have been so many issues and challenges faced the cloud computing providers. Most of these are related to how to secure the user authentication which is seen as a core requirement for the cloud computing system the personal authenticating data of user becomes susceptible to a variety of attacks like password guessing, denial of service (DOS), replay, man-in-the-middle, insider, and so on. As a result, there has been a wide range of techniques and methods proposed to prevent such attacks and provide sufficient security for the user authentication in the cloud system. Yet, some of the issues such as mutual authentication, verification, and the impossibility of freely password change still remain unsolved. Therefore, there is a must to provide a strong user authentication scheme to solve such problems. This paper proposes a new strong scheme for cloud computing authentication by using USB token with a combination of hash function and Diffie-Hellman key exchange. The proposed scheme is so secure and effective as it attains the requirements of functionality and security.
