 The lock code is so complex that the car thief gives up there as a prototype. And the problem with such locks is resolved. The remote-control bill ridge has the drawback that the encryption is not strong enough to stop a car thief from home to fill up tone when someone hangs up his car, crack the code and create a "dublettnyckel" to the car. The code breaking for a few years ago, and automakers develop new algorithms to make key codes more efficient. The weakness is that the algorithms are symmetrical, the code can be found in both key in the car. In addition, the encoded information in lots of cars offs the production line. This code is cracked by cars risk. Researchers at the Fraunhofer Institute for secure information technology, SIT, have developed an asymmetric algorithm for a remote key. The drawback of such solution is the high computing power needed to read the code. With such a technique would be the battery in the car key to have run out in a short time. However, scientists have developed a crypto chip to save energy and a protocol for the calculations can be minimized. The battery in the key is to keep as long as the battery in today's remote-control locks. The lock will be presented at the exhibition Embedded World trade show in Nuremberg in early March. |
