Fuming Acid, Reverse Engineering and Cryptanalysis: Open Sesame in the 21st Century

Lecture:   Fuming Acid, Reverse Engineering and Cryptanalysis: Open Sesame in the 21st Century
Lecturer:     Timo Kasper
Date and time: 21st October 2013, 6–7:30 p.m.
Place:       FIT CTU in Prague, 9 Thákurova Street, New Building CTU, lecture room T9:107


The talks sums up two recent papers (CRYPTO 2013 [1] and SAC 2013 [2]) about breaking an electronic locking system. After an introduction to (electronic) locking systems and cryptography, Timo will sum up found security flaws and vulnerabilities in commercial products for access control. Recent improvements of the open-source card emulator "chameleon" for Mifare and other cards will be presented. As the main part, a recent security analysis of a widespread electronic locking system (used in banks, prisons, airports and other high security venues worldwide) is presented: The combination of reverse-engineering, side-channel analysis and mathematical cryptanalysis reveals weaknesses in the system that allow opening secured doors in seconds.
