German researchers crack RFID smartcard encryption - Technology - GMA News Online - Latest Philippine News: "German researchers have cracked the encryption used to protect a type of smartcard whose functions range from restricting access to buildings to processing public transit system payments.
The team demonstrated a hack that can duplicate the magnetic security card and break a previous version of contactless ID cards from Mifare in 2008, The Hacker News reported.
"The new hack is carried out using a side channel attack, which bypasses the defensive features intended to prevent attacks on the card. To achieve this, the researchers made repeated measurements of electricity consumption during encryption and decryption. This can be determined by measuring the magnetic field close to the card," The Hacker News said.
