AI-Accelerated Brute Force Cryptanalysis
Modern cryptography is hinged on "not learning from mistakes": trying numerous wrong keys, should not help one identify the right key. Indeed, it worked -- until recently when the surprising power of AI to see pattern in apparent randomness has turned the 'wrong plaintexts' generated by the 'wron...
CVE-2025-14505
The ECDSA implementation of the Elliptic package generates incorrect signatures if an interim value of 'k' as computed based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 has leading zeros and is susceptible to cryptanalysis, which can lead to secret key exposure. This...
CVE-2025-14505
The CVE-2025-14505 entry concerns Elliptic’s ECDSA implementation. A fault in the ECDSA signing path occurs when the interim value of k (per RFC 6979 step 3.2) has leading zeros, causing the byte-length of k to be computed incorrectly and truncated. This can allow cryptanalytic leakage of the sec...
CVE-2025-14505 Elliptic Cryptanalysis vulnerability when `k` has leading zeros
The ECDSA implementation of the Elliptic package generates incorrect signatures if an interim value of 'k' as computed based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 has leading zeros and is susceptible to cryptanalysis, which can lead to secret key exposure. This...

Cryptanalysis of Pseudorandom Error-Correcting Codes
Pseudorandom error-correcting codes PRC is a novel cryptographic primitive proposed at CRYPTO 2024. Due to the dual capability of pseudorandomness and error correction, PRC has been recognized as a promising foundational component for watermarking AI-generated content. However, the security of PR...
ALTCHA 安全漏洞
ALTCHA is a self-hosted CAPTCHA software from ALTCHA Open Source. A security vulnerability exists in ALTCHA that stems from a cryptanalysis flaw that could lead to the recovery of random numbers through mathematical derivation...
The Star Product of Uniformly Random Codes
We consider the problem of determining the expected dimension of the star product of two uniformly random linear codes that are not necessarily of the same dimension. We achieve this by establishing a correspondence between the star product and the evaluation of bilinear forms, which we use to...

New Cryptanalysis of the Fiat-Shamir Protocol
A couple of months ago, a new paper demonstrated some new attacks against the Fiat-Shamir transformation. Quanta published a good article that explains the results. This is a pretty exciting paper from a theoretical perspective, but I don't see it leading to any practical real-world cryptanalysis...
Wrangling Entropy: Next-Generation Multi-Factor Key Derivation, Credential Hashing, and Credential Generation Functions
The Multi-Factor Key Derivation Function MFKDF offered a novel solution to the classic problem of usable client-side key management by incorporating multiple popular authentication factors into a key derivation process, but was later shown to be vulnerable to cryptanalysis that degraded its...
1965 Cryptanalysis Training Workbook Released by the NSA
In the early 1960s, National Security Agency cryptanalyst and cryptanalysis instructor Lambros D. Callimahos coined the term "Stethoscope" to describe a diagnostic computer program used to unravel the internal structure of pre-computer ciphertexts. The term appears in the newly declassified...
Cryptanalysis of LC-MUME: a Lightweight Certificateless Multi-User Matchmaking Encryption for Mobile Devices
Yang et al. proposed a lightweight certificateless multiuser matchmaking encryption LC-MUME scheme for mobile devices, published in IEEE Transactions on Information Forensics and Security TIFS DOI: 10.1109/TIFS.2023.3321961. Their construction aims to reduce computational and communication overhe...
