Abstract
Αs technologies and communications develop, more sabotaging attacks occur including phishing attacks which jeopardize users' security and critical information like their passwords and credentials. Several solutions have been proposed for existing dangers. One of which is the use of one-time passwords. This issue has remained as a main challenge and requires more extensive research. In this research, we have focused on one-time password combinations and we also have proposed solutions based on behavioral patterns which lead to significant optimizations while tending the simplicity for users. Efficiency of the proposed method has been measured through defining scenarios, modeling and simulations based on a prevention rate index. In addition, complexity coefficient of the proposed method showing the probability of unpredictability of passwords for attackers has been calculated. Ultimately, a descriptive comparison has shown that the proposed method is superior to some of the existing methods.
Highlights
Electronic banking continuously requires new methods aimed at improvement of security, with respect to the extensiveness of bank, commercial and personal transactions and that most of them are conducted on the internet
In order to make this simulation as simple as possible, we assumed that the phishing attack was partially successful and the attacker has been able to hypothesize a primary combination for the one-time passwords (OTPs)
In this research we proposed a combined method for prevention of phishing attacks based on visual, text and behavioral patterns which is relative to the number of selected factors for behavioral patterns and can reduce significantly the rate of phishing attacks success
Summary
Electronic banking continuously requires new methods aimed at improvement of security, with respect to the extensiveness of bank, commercial and personal transactions and that most of them are conducted on the internet. Using one-time passwords for functions including authentication, improves the security of transactions, and can be used for prevention of attacks aimed at stealing users' information. These types of attacks are known as phishing attacks. Authors in [2] proposed a method for prevention of phishing attacks This method uses keywords to validate the originality of webpages. By this means direction of users' towards fake pages is prevented. Authors in [6] proposed a method for prevention of phishing threats in websites This method benefits from a visual encryption by making use of images and OTP. This method can be a suitable alternative for typed passwords
