How AES Breaks in Real Life: The Attacks That Never Touched the Cipher
AES-the-cipher has never been broken in the field -- its deployments have. KRACK, repeated GCM nonces, and cache timing broke the wrapper, never the block.

One Number, Used Twice: How a Repeated Nonce Hands Over Your Private Key -- and How Determinism Takes It Back
A repeated ECDSA nonce leaks your private key with grade-school algebra; a reused AES-GCM IV forges ciphertext. Why -- and how determinism fixes both.
