Systems and models for secure fallback authentication
Fallback authentication (FA) techniques such as security questions, Email resets, and SMS resets have significant security flaws that easily undermine the primary method of authentication. Security questions have been shown to be often guessable. Email resets assume a secure channel of …

Design and analysis of light-weight symmetric cryptographic frameworks and constructs for secure packet mode wireless communication
… framework for data packet integrity and authentication security services is proposed and described. The Quicker Block Chaining (QBC) family of message authentication constructs designed using the framework, are shown, via software simulation, to operate with better efficiency (i.e. uses …

Product Authentication Using Hash Chains and Printed QR Codes
… simplistic nature of such printed codes, many security issues like tag impersonation, server impersonation, reader impersonation, replay attacks and denial of service present in RFID based solutions need to be handled differently. An algorithm that utilizes hash chains to secure such simple …

Location Based Authentication
… of a genuine user. Today's conventional authentication mechanisms are based on three factors: knowledge, possession and biometrics. These factors are prone to theft, hardware failure, expensive, etc. Consequently, there is a need of a stronger solution. One such solution is Location Based …

Raising the bar for password crackers: improving the quality of honeywords with deep neural networks
Honeywords are fictitious passwords inserted into databases in order to identify password breaches. Producing honeywords that are difficult to distinguish from actual passwords automatically is a time-consuming and sophisticated task, and the majority of existing research assumes that attackers …
