Forgery Attacks on Several Beyond-Birthday-Bound Secure MACs
, 2023 At CRYPTO’18, Datta et al. proposed nPolyMAC and proved the security up to 22𝑛/3 authentication queries and 2𝑛 verification queries. At EUROCRYPT’19, Dutta et al. proposed CWC+ and showed the se- curity up to 22𝑛/3 queries. At FSE’19, Datta et al. proposed PolyMAC and its key-reduced variant 2k-PolyMAC, and showed the security up to 22𝑛/3 queries. This

Nonce-Disrespecting Adversaries:Practical Forgery Attacks on GCM in TLS
IACR Cryptol. ePrint Arch., 2016 We investigate nonce reuse issues with the GCM block cipher mode as used in TLS and focus in particular on AES-GCM, the most widely deployed variant. With an Internet-wide scan we identified 184 HTTPS servers repeating nonces, which fully breaks the authenticity of the connections.

Detecting Audio Copy-Move Forgeries on Mel Spectrograms via Hybrid Keypoint Features
Applied SciencesWith the widespread use of audio editing software and artificial intelligence, it has become very easy to forge audio files. One type of these forgeries is copy-move forgery, which is achieved by copying a segment from an audio file and placing it in a ...
