Abstract: Comparing with traditional IT system, cloud computing presented the new characteristics of virtualization, multiuser, distributed and so on. Most existing authentication mode such as “userid+password” faced the risks such as fraudulent use and maninthemiddle attacks in the high security field. In view of this, this paper proposed a solution for implementing cloud identity authentication in a high security environment. The USBKey is used in the cloud terminal, and the twofactor strong identity authentication is realized by utilizing the “USBKey+PIN code”, and it is combined with the digital certificate technology to enhance the existing remote desktop protocol (RDP). The USBKey is safely mapped onto the virtual desktop to estabilsh a secure connection channel. and the strong identity authentication for the user to log into the cloud server is realized. This solution issuccessfully applied to our science and technology Big Data platform of our college, and achieved good results.
