Cryptanalysis of the Fast Lightweight Mutual Authentication Protocol

Abstract

Security counts as a critical barrier to continuing growth of RFID industry due to lack of a proper high performance lightweight protocol-based solution. Amongst recent developments the Fast Lightweight Mutual Authentication Protocol (FLMAP) has been accepted for its superior speed and low complexity features. Here we examine the security strengths of FLMAP through systematic cryptanalysis tests. Outcome of our investigation show that in spite of its superior speed and power saving features FLMAP shows some serious design gaps and shortfalls against two specifically selected desynchronization and ID disclosure attacks. Finally, we propose solutions to fix the FLMAP designing and security flaws.
