CVE-2026-22001-SPHINCS-WOTS-Weak-Randomness-Forgeable-Signature

CVE-2026-22001 – SPHINCS+ WOTS+ の弱い乱数による署名偽造 概要 SPHINCS+ ポスト量子署名スキームの実装は、WOTS+ 署名生成時に欠陥のある乱数生成器を使用します。同じナンス k が複数の署名にわたって再利用されるため、攻撃者は秘密鍵を復元し、任意のメッセージを偽造できます。 脆弱性の詳細 タイプ: 暗号学的乱数生成の失敗 影響: 鍵の完全な漏洩、署名偽造。 根本原因: WOTS+ 署名アルゴリズムは、署名ごとに一意の乱数値 k に依存します。k の再利用により、シードを明らかにする代数的関係が漏洩します。 エクスプロイトの実証...

RUSTSEC-2026-0160 `pqcrypto-sphincsplus` is unmaintained: upstream PQClean project being archived

This crate provides Rust bindings to SPHINCS+/SLH-DSA FIPS 205 via C implementations from PQClean.

A Survey of Post-Quantum Cryptography Support in Cryptographic Libraries

The rapid advancement of quantum computing poses a significant threat to modern cryptographic systems, necessitating the transition to Post-Quantum Cryptography PQC. This study evaluates the support for PQC algorithms within nine widely used open-source cryptographic libraries -- OpenSSL, wolfSSL...

Quantum-Resistant Domain Name System: a Comprehensive System-Level Study

The Domain Name System DNS plays a foundational role in Internet infrastructure, yet its core protocols remain vulnerable to compromise by quantum adversaries. As cryptographically relevant quantum computers become a realistic threat, ensuring DNS confidentiality, authenticity, and integrity in t...

Post Quantum Cryptography (PQC) Signatures without Trapdoors

Some of our current public key methods use a trap door to implement digital signature methods. This includes the RSA method, which uses Fermat's little theorem to support the creation and verification of a digital signature. The problem with a back-door is that the actual trap-door method could, ...

A Scalable Framework for Post-Quantum Authentication in Public Key Infrastructures

This work explores the performance and scalability of a hierarchical certificate authority framework with automated certificate issuance employing post-quantum cryptographic PQC signature algorithms. The system is designed for compatibility with both classical and PQC algorithms, promoting...
