Title:
Partial Differential Fault Analysis on Ascon
Authors: Yang Gao
Abstract:Authenticated Encryption with Associated Data (AEAD) is a trend in applied cryptography because it combine confidentiality, integrity, and authentication into one algorithm and is more efficient than using block ciphers and hash functions separately. The Ascon algorithm, as the winner in both the CAESAR competition and the NIST LwC competition, will soon become the AEAD standard for protecting the Internet of Things and micro devices with limited computing resources. We propose a partial differential fault analysis (PDFA) technology for the Ascon algorithm, using stuck-at fault and random-nibble fault models respectively. Theoretically, after 9.9 full-round fault injections or 263 single nibble fault injections, 128-bit key can be completely recovered. In addition, we conducted the first discussion of this analysis method under different nonce configurations. In the Nonce-respect case, an average of 130 additional Tag queries are required to complete the guessing of the faulty tag, afterwards equating this case with the Nonce-misuse case. Subsequent experimental results proved the correctness of the theoretical model. Finally we discuss some countermeasures against proposed attacks, and we propose a new S-box that can be used to replace the existing S-box in ASCON to render PDFA ineffective.
