How Elliptic Curves and Diffie-Hellman Break in Real Life: The Discrete Log Never Fell
No one has solved the discrete log on a strong curve or a 2048-bit group -- yet PS3, Android wallets, TPMs, CurveBall, and Logjam all fell. Here is exactly how.

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.

The Math Held; The Interface Leaked: A Field Guide to Digital Signatures
ECDLP and RSA held; the nonce, the canonical form, and the verifier broke instead. A field guide to ECDSA, EdDSA, RSA-PSS, determinism, and malleability.

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.
