Spinel: A Post-Quantum Signature Scheme Based on SLn(Fp) Hashing

The advent of quantum computation compels the cryptographic community to design digital signature schemes whose security extends beyond the classical hardness assumptions. In this work, we introduce Spinel, a post-quantum digital signature scheme that combines the proven security of SPHINCS+ CCS...

CVE-2020-36843

The implementation of EdDSA in EdDSA-Java aka ed25519-java through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA Strong Existential Unforgeability under Chosen Message Attacks property. This allows attackers to create new valid signatures different from previous signature...

SHA-1 Broken

HA-1 Broken SHA-1 has been broken. Not a reduced-round version. Not a simplified version. The real thing. The research team of Xiaoyun Wang, Yiqun Lisa Yin, and Hongbo Yu mostly from Shandong University in China have been quietly circulating a paper describing their results: collisions in the the...

[OpenCA Advisory] Vulnerabilities in signature verification

OpenCA Security Advisory 28 November 2003 Vulnerabilities in signature validation ======================================= Multiple flaws in OpenCA before version 0.9.1.4 could cause OpenCA to use an incorrect certificate in the chain to determine the serial being checked which could lead to...
