In the current form, existing 2FA systems are defenseless against phishing attacks. They do not provide any visual indicator to the user to check the website’s validity before logging in during phishing attacks. This exposes the user’s password during the phishing attack. Two-factor authentication needs to be enhanced to provide a mechanism to detect phishing attacks without adding a significant burden on the user. This research paper will propose a novel 2-FA TOTP mechanism to provide a subconscious indicator during a phishing attack. In comparison, the new proposed novel approach provides better security against phishing attack. Lastly, the mathematical analysis is performed to understand the TOTP variance and validate the security considerations against the existing 2FA systems with respect to adversary attack.展开更多

This exposes the network subscribers to identify theft and users data to security threats like snooping, sniffing, spoofing and phishing. There is need to curb these problems with the use of an enhanced multi-factor authentication approach. The objective of this work is to create a multi-factor authentication software for a 4G wireless network. Multi-factor authentication involves user’s knowledge factor, user’s possession factor and user’s inherence factor;that is who the user is to be presented before system access can be granted. The research methodologies used for this work include Structured System Analysis and Design Methodology, SSADM and Prototyping. The result of this work will be a Multi-factor authentications software. This software was designed with programming languages like ASP. NET, C# and Microsoft SQL Server for the database.展开更多

Li <i>et al</i>. proposed a three-factor anonymous authentication scheme in WSNs over Internet of things (IoT). They argued that their authentication scheme achieves more security and functional features, which are required for WSNs over IoT. Especially, they insisted that their user authentication scheme provides security against sensor node impersonation attack, and resists session-specific temporary information attack and various other attacks. However, this paper shows some security weaknesses in Li <i>et al</i>.’s scheme, especially focused on sensor node masquerading attack, known session-specific temporary information attack and deficiency of perfect forward secrecy. Especially, security considerations are very important to the modern IoT based applications. Thereby, the result of this paper could be very helpful for the IoT security researches.展开更多

Besides this, in our proposed scheme the password is no longer involved in the calculation of verification phase which makes our scheme more secure and costs less than the old one. At last we analyze the performance of our proposed scheme to prove it provides mutual authentication between the user and the server. Moreover, it also resists password guessing attack, server and user masquerade attack and replay attack effectively.展开更多

The codes may originate from different entropy attributes and schemes, such as true random and digital random number generators. Businesses, organizations, and academic institutions have adopted OTP methods for credit card transaction confirmation, recalling forgotten passwords, and validating web portal accounts. This paper proposed a new method in authenticating login credentials using a 3 × 3 matrix and random system key as Two-Factor Authentication (2FA) with an SMS-enabled feature. We used the 6-codes pseudorandom method and a 4-codes validation to allow mobile flexibility and ensure that the user has the required access. The page link and evaluation form are sent to students, IT professionals, and researchers. The results showed respondents are satisfied in terms of functionality, usability, efficiency, and reliability. The developed system could safeguard information, disallow unauthorized access, and impose acceptable data protection measures and minimal system requirements to use the system.展开更多
