MUNICH, Germany — The Chaos Computer Club (Hamburg, Germany) has cracked the encryption scheme of NXPs popular Mifare Classic RFID chip. The device is used in many contactless smartcard applications including fare collection, loyalty cards or access control cards. NXP downplays the significance of the hack.

According to a report in Sueddeutsche Zeitung, Chaos Computer Club (CCC) experts along with colleagues from the University of Virginia cracked the encoding scheme with little effort. The achievement allows the crackers to read out data, recharge payment cards, copy RFID cards or generate "new" users.

The Mifare Classic family is sold in large volumes. Its memory sports a capacity of 1 to 4 kByte, explained a spokesperson in NXPs Austrian RFID competence center. Since it is in the market since the mid-nineties, the proprietary 48-bit encoding scheme is not necessarily up to today's requirements. Nevertheless, NXP sees no necessity to modify the encryption.

The spokesperson pointed out that the company also offers other RFID chips with higher security up to Triple DES or AES. "We will inform our customers about the incident", the spokesperson said. But it is the decision of the system integrator or customer if he will continue to rely on the Mifare Classic. "There are certainly applications for which the Classic can be used. We have not plans to withdraw the product from the market."

The spokesperson also pointed out that the Mifare Classic is not used in security-critical applications such as passports or electronic health cards.

The Chaos Computer Club was not available for comment.

You are wrong. That is exactly why RFID will be implemented! If the stuff would be 100% secure then the goverment and the people "behind" wouldnt want it. The reason is easy. The CIA, MI6, etc. need backdoors and stuff. This allows them to enter every building, to spy every computer etc. to have access to everything and everywhere.

It will be sold and reported as 100% secure to us, but there will always be a backdoor or some kind of security flaws in it so the people "behind" are able to do what they want with it. Etc. steal your money, have access to a secure airport room etc. Also we dont even have to think that far. Just think about the official law enforcement. They are already able to read the whole adress book of every cell phone, even without the pin number. If the law enforcement has to enter a secure building cause there are some terrorists inside then they will want to have a "master key card" to open that RFID secured door in the building. So the stuff cannot be 100% secure cause then the lawenforcment wouldnt be able to open the door without blowing it up.
