Access Without Permission A Practical RFID Relay Attack Proximity >50m via Bluetooth Roman Silberschneider, Thomas Korak, and Michael Hutter, Austrochip 2013
Mobile Security Research Results Mobile devices as RFID reader platforms Security/privacy vulnerabilities of reader platform might impact the security/privacy of IoT applications E.g. (data dependent) information leakage during computations Execution times Power consumptions EM emanations 9
Timing Attacks (1) Exploit execution times of secret computations to recover secret data (e.g., cryptographic key) Why does the execution time vary? Conditional execution of instructions Retrieving data from different memory locations Cache access Data retrieval almost immediately Main-memory access Data retrieval takes more time 10
Timing Attacks (2) Approach Gather measurement samples of multiple AES encryptions Statistical analysis of execution times recover (parts) of the secret key Results 3 mobile devices (tablets and smartphones) Reduced 128-bit AES key to ~58-bit AES key potential security vulnerability For further information see list of publications at http://www.comet-secos.at 11
