RFID Noisy Reader How to Prevent from Eavesdropping on the Communication?

چکیده
RFID applications do not always use encryption to ensure the security as public key cryptographic algorithms that are costly in term of computing resources. We proposed to secure the communication from an ISO 14443 RFID card to the reader against passive eavesdropping at the physical layer by adding noise. During the card reply, the reader generates an appropriate noise that is modulated by the load of the card. By knowing the noise it emitted, the reader is able to subtract it and to retrieve the card message when a spying probe in the field is inefficient.

Noisy Carrier Modulation for HF RFID
Radio-frequency tokens are vulnerable to eavesdropping. Several schemes have been proposed that use additional devices to generate cover noise, or bit collisions, in order to protect communication between a reader and a token. I discuss the practical weaknesses in current bit-blocking schemes and propose an alternative implementation where the tokens modulate their reply onto a noisy carrier pr...

Radio frequency identification (RFID) is a new generation of automatic identification systems, based on wireless communication technology. In these systems all the tags using one communication channel to communicate with the reader. When two or more tags transmit their data to the reader simultaneously, their transmitted signals will collide. Resolving this collision has a direct impact on the ...
