Electromagnetic analysis and attacks system for cryptographic RFID

An electromagnetic (EM) analysis and attacks system has been designed for cryptographic Radio Frequency Identification Devices (RFID). The system has the function of carrier removing in analog front-end with adaptive carrier obtain and EM shielding, finding the best acquisition position base on multiple feedback judgment, preprocessing and analysis with drift elimination and noise reduction. Analysis is performed on a practical 13.56M RFID, the Triple-DES (3DES) operation time is located with 1400 curves, and the key of 3DES is recovered with 14000 curves using preprocessing with drift elimination and noise reduction.
