In real estate and vehicles there is an increasing demand for the comfort of wireless technology. Transponders, contactless smartcards and remote door openers are widely employed to replace conventional mechanical key locking systems. Our scientific analyses show, that the mechatronic locking systems – although using mature mechanical security technology – often suffer from vulnerabilities within the electronic system, the employed cryptography or conceptual weaknesses. The protection mechanisms can then often be thwarted by means of rather simple and efficient methods, such that adversaries may, e.g., copy electronic keys or deactivate alarm systems.<\/p>\n

At the example of the KeeLoq© system – a system widely employed for garage door remotes \u2013 and many other remote keyless entry systems, history has shown that the employed protection mechanisms fail to resist determined attackers. Due to the usage of radio interfaces the impact of successful attacks are much more severe than in conventional mechanical systems, as there is no need for an attacker to have physical access to the targeted system.<\/p>\n
