AES-128 (Advanced Encryption Standard with 128-bit key) is the current industry standard for NFC chip security. Adopted by NIST in 2001, it provides strong symmetric encryption with no known practical attacks. AES-128 is used in MIFARE DESFire EV2/EV3, NTAG 424 DNA, MIFARE Ultralight AES, and most modern secure NFC applications.

Known Vulnerabilities
Current industry standard. No known practical attacks against the full 14-round AES-128. Theoretical biclique attack reduces security to ~126.1 bits, which remains computationally infeasible.
