More NFC Phones Coming To The West
Same ole RFID, Same ole Security/Privacy Issues
Although the communication range of NFC is limited to a few centimeters, NFC alone does not ensure secure communications. In 2006, Ernst Haselsteiner and Klemens Breitfuß described different possible types of attacks.
NFC offers no protection against eavesdropping and is also vulnerable to data modifications. Applications have to use higher-layer cryptographic protocols (e.g., SSL) to establish a secure channel.
Eavesdropping
The RF signal for the wireless data transfer can be picked up with antennas. The distance from which an attacker is able to eavesdrop the RF signal depends on numerous parameters, but is typically a small number of meters. For example, eavesdropping is extremely affected by ...
