Zusammenfassung:

KeeLoq remote keyless entry systems are widely used for access control purposes such as garage door openers or car anti-theft systems. We present the first successful differential power analysis attacks on numerous commercially
available products employing KeeLoq code hopping. Our new techniques combine
side-channel cryptanalysis with specific properties of the KeeLoq algorithm.
They allow for efficiently revealing both the secret key of a remote
transmitter and the manufacturer key stored in a receiver. As a result, a
remote control can be cloned from only ten power traces, allowing for a
practical key recovery in few minutes. Once knowing the manufacturer key, we
demonstrate how to disclose the secret key of a remote control and replicate it from a distance, just by eavesdropping at most two messages. This key-cloning without physical access to the device has serious real-world security implications. Finally, we mount a denial-of-service attack on a KeeLoq access control system. At the end of the talk we will present a demonstration of the attack on a commercial KeeLoq product.
