RC3: The heavy collateral damage of the first Crypto was

What have millions of insecure rfid chip cards, which are used, among other things, for access controls, and an increasing number of car hells with the rings to do secure sealing? For ross anderson a lot. The professor of security engineering at the university of cambridge pays these phenomena to the heavy collateral damage of the first round of the continued crypto wars of the 1990s.

At that time, the us government tried under prasident bill clinton to largely prevent the export of hardware and software for secure closure procedures and also destroy us burger when using cryptographic solutions with the clipper chip. Scientists and burgerechtler had already warned that with such restrictive politics the it security has been massively affected. It only helps criminals if the industry consciously install weaknesses in their products must not be closed or laughing in the interest of security robes.

Blockade with consequences

Us deputy presentation al gore officially ended the fight against the it economy in 2000. However, the massive consequences are still trailable, anderson explained on monday on the remote chaos communication congress (rc3). According to anderson, for example, all wireless attenuation systems of cars use insufficient shutters. Therefore, it is not surprised that the number of car help meters has almost doubled in recent years. Although not all these deeds are due to weak suspension. The crypto was guided into a false culture in this area.

Frost-proof

Frost-proof

Munich, 5. October 2015 – the nowhere stipulated rule according to which winter tires should be fitted between october and easter is still justified. If you need new tires, you should take care of them now at the latest, because the night temperatures are already quite low. In addition, the phenomenon repeats itself every year that many motorists are completely surprised by the sudden onset of winter and then hectic activity ensues. As a result, for a short time, tire dealers are the most sought-after craftsmen in the country.

Define criteria yourself

The society for technical monitoring (gtu) and the autoclub europa (ace) have tested eight 225/50 r17 tires from well-known manufacturers. Now, winners in tire tests should be viewed just as critically as with other product groups, as different consumers also have different evaluation criteria: the infrequent driver will hardly be interested in the wear resistance and rolling resistance, whereas a frequent driver will certainly be interested. Regardless of this, however, it turns out that the price should not be the sole decisive purchase criterion. According to prufern, there is around 160 euros between the most expensive and the cheapest tire set – a lot of money, especially since both are close together in terms of properties. However, with a higher mileage or a lower rolling resistance, such differences can quickly cancel each other out over the service life of a tire.

Overall, the testers from gtu and ace see the conti ts850 in the lead. The candidates from goodyear and dunlop ended up just behind. None of them afford gross weaknesses in a chapter. Nevertheless, it is worth taking a look at the detailed results. The penultimate tire in the test, the one from semperit, is one of the best on snow when it comes to traction and braking. Its running noise is also particularly quiet. When braking on a dry road, the noisy pirelli is right at the front. These examples make it clear that it can be worthwhile to look further than the tire labels. Under certain circumstances, a candidate can be found who is good in the criteria perceived as important and ultimately cheaper than the test winner.
