A Authentication model to Trustees based Social Networks
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
authenticating users with the help of their friends has been shown to be a promising backup authentication mechanism. A user in this system is associated with a few trustees that were selected from the user’s friends. When the user wants to regain access to the account, the service provider sends different verification codes to user’s trustees. The user must obtain at least k reset his or her password. In this paper, we provide the first systematic study about the security of trustee based social authentications. In particular, we first introduce verification codes from the trustees before being directed to small framework of attacks, which attacks. In these attacks, an attacker initially obtains we call forest fire iteratively, attacks the rest of users by exploiting trustee-based social authentications. Then, we construct a probabilistic model to for attackers. Moreover, we introduce number of compromised users, and then the attacker a novel various defense formalize the threats of forest fire attacks and their costs strategies. Evaluate various concrete attack and defense our results have finally, we apply our framework to strategies using three real world social network datasets. Extensively strong implications for the design of more secure trustee-based social authentications.
