An Efficient Authentication Scheme for Mobile Online Social Networks

With the immense growth of smartphones and mobile Internet, it has become easier to access online social networking sites, such as Facebook, Twitter, LinkedIn, and so on. At the same time, attackers also utilized this opportunity very well by introducing the innovative idea of attacks. Phishing was a classical technique of information stealing. According to the published reports [1], the rate of phishing attacks has increased much more during the last few years. Earlier an adversary sends an email with malicious URLs in it. But in OSN, an attacker creates a scam website of an important website and posts the link on the wall of the OSN users. When the user tries to open and login into the site, the attacker easily steals the private information, such as passwords and credit card numbers. In this paper, we proposed an efficient authentication scheme that can resist phishing attacks and some other known security threats also. Finally, we analyze and show that the scheme provides better security against phishing attacks and other known attacks.
