Abstract :

Internet provides different types of services to the users. Electronic mail, chat, photo sharing and social network services are provided by the Internet community. Most of the Internet services perform the user authentication using passwords. Password forgets and password changed by attackers requires user verification with security questions and alternate e-mail account support. Backup authentication mechanisms such as security questions and alternate email addresses are insecure or unreliable or both Friends based verification is one of the 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 the user’s trustees. The user must obtain at least k verification codes from the trustees before being directed to reset his or her password. Forest fire attacks are applied on the trustee based social authentication scheme. In forest fire attacks an attacker initially obtains a small number of compromised users and then the attacker iteratively attacks the rest of users by exploiting trustee-based social authentications. A probabilistic model is constructed to formalize the threats of forest fire attacks and their costs for attackers. Various defense strategies are used to verify the forest fire attacks. The framework is applied to extensively evaluate various concrete attack and defense strategies using three real-world social network datasets.  The forest fire attack handling mechanism is enhanced with time bounded verification strategies. Two level trustee based verification model can be introduced to improve the social authentication process. Multiple service based authentication can be used in the attack defending process.
