Explainable PQC: A Layered Interpretive Framework for Post-Quantum Cryptographic Security Assumptions
This paper studies how post-quantum cryptographic PQC security assumptions can be represented and communicated through a structured, layered framework that is useful for technical interpretation but does not replace formal cryptographic proofs. We propose "Explainable PQC,'' an interdisciplinary...
Breaking ECDSA with Two Affinely Related Nonces
The security of the Elliptic Curve Digital Signature Algorithm ECDSA depends on the uniqueness and secrecy of the nonce, which is used in each signature. While it is well understood that nonce $k$ reuse across two distinct messages can leak the private key, we show that even if a distinct value i...
DEBIAN-CVE-2024-1544
Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Meaning k = r mod n. The division used during the reduction estimates a factor qe by dividing the upper two digits a digit having e....
