Dismantling Megamos Crypto: Wirelessly Lockpicking a Vehicle Immobiliser

Lisa O’Carroll:

A British-based computer scientist has been banned from publishing an academic paper revealing the secret codes used to start luxury cars including Porsches, Audis, Bentleys and Lamborghinis as it could lead to the theft of millions of vehicles, a judge has ruled.
The high court imposed an injunction on the University of Birmingham’s Flavio Garcia, a lecturer in computer science, who has cracked the security system by discovering the unique algorithm that allows the car to verify the identity of the ignition key.

The UK injunction is an interim step in a case launched by Volkswagen’s parent, which owns the four luxury marques, against Garcia and two other cryptography experts from a Dutch university.

It complained that the publication could “allow someone, especially a sophisticated criminal gang with the right tools, to break the security and steal a car”. The cars are protected by a system called Megamos Crypto, an algorithm which works out the codes that are sent between the key and the car.

“Best Drivers Report”. Where do American Cities Rank?

Allstate:

Car crash fatalities are at the lowest level they’ve been since 1949, but still average more than 32,000 every year, according to the National Highway Traffic Safety Administration.

“It is vital for us to educate American drivers about safe driving behaviors they can demonstrate on the road that will help make our roadways safer,” said Roche. “Minimizing distractions, obeying traffic laws, and using your car’s safety features like turn signals and headlights, are all ways to be safer, no matter where you drive.”
Big-city vs. Small-city Driving
Different levels and types of traffic, noise and activity, as well as varying road conditions and rules, can make big city driving different than driving in smaller cities or more suburban areas. Allstate offers the following tips for driving in both settings. In larger cities:

The first task is to consider mileage. The Center for Neighborhood Technology’s Housing and Transportation Affordability Index estimates the number of miles that members of an average household travel by car in a year, broken down by city. Among our candidates, the average is 14,433 miles. (Garland, Tex., tops our list at 19,234 miles, while New York City is at the bottom with 9,375). We’ll incorporate this information into the data by creating a multiplier based on how many miles a city’s residents drive relative to the average. The Allstate rankings, for example, are based on the number of years between accidents. San Franciscans average 6.5 years between crashes, but they drive 74 percent as many miles as the average for cities in our survey, so we lower their years-between-accidents to 4.8 to account for how rarely they drive.
