Systematic Timing Leakage Analysis of NIST PQDSS Candidates: Tooling and Lessons Learned

The PQDSS standardization process requires cryptographic primitives to be free from vulnerabilities, including timing and cache side-channels. Resistance to timing leakage is therefore an essential property, and achieving this typically relies on software implementations that follow constant-time...

CVE-2025-27587

OpenSSL 3.0.0 through 3.3.2 on the PowerPC architecture is vulnerable to a Minerva attack, exploitable by measuring the time of signing of random messages using the EVPDigestSign API, and then using the private key to extract the K value nonce from the signatures. Next, based on the bit size of t...
