Multi-layered crypto cloud integration of oPass

One of the most popular forms of user authentication is the Text Passwords. It is due to its convenience and simplicity. Still, the passwords are susceptible to be taken and compromised under various threats and weaknesses. In order to overcome these problems, a protocol called oPass was proposed. A cryptanalysis of it was done. We found out four kinds of attacks which could be done on it i.e. Use of SMS service, Attacks on oPass communication links, Unauthorized intruder access using the master password, Network attacks on untrusted web browser. One of them was Impersonation of the User. In order to overcome these problems in cloud environment, a protocol is proposed based on oPass to implement multi-layer crypto-cloud integration with oPass which can handle this kind of attack.
