Multi-layered crypto cloud integration of oPass

Abstract: 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.

Cryptanalysis of oPass

Abstract: The security of oPass: A User Authentication Protocol Resistant to Password Stealing and Password Reuse Attacks proposed by HMSun et al in IEEE Transactions on Information Forensics and Security, Vol7, No2, April 2012 is analyzed Upon completion of the analysis of the paper, four kinds of attacks SMS service, attacks on oPass communication links, unauthorised intruder access using the master password and Network attacks on untrusted web browser are identified in different scenarios Thus, we proved that oPass proposed by HMSun et al is not suitable for practical application
