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. The PQClean project is being archived in or after July 2026 see PQClean/PQClean604, after which no further security patches or bug fixes will be applied to the upstream implementations. As a result,...

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...
