%X Cloud computing is a service-oriented computational platform that allows on-demand  resource provisioning for low-cost application deployment.   However, security and privacy of  the users is a major concern for the cloud 
service  provider,  particularly    for  applications  handling  users  personal  information  (health  record,  GPS  location)  or  performing financial transactions. Authentication is an important security  measure  for establishing accountability and 
authorization of  the users, is often a prerequisite for accessing cloud-based services. In this paper, we mainly focus on the 
token-based authentication techniques, supported by popular open source cloud platforms [OSCPs], like  Cloudstack, 
OpenStack,  Eucalyptus  and  OpenNebula.  In  general,  most  OSCPs  support  the  basic  text-based  user  authentication.  
Other techniques,  such as biometrics, gesture and image, can also be implemented on OSCPs. However, in this paper, 
we choose to discuss the token-based authentication, as it allows users to gain access to multiple cloud services with a 
single sign-on (SSO). Moreover, token’s can be shared among multiple users for accessing cloud-based services..
