wolfSSL is pleased to share a case study with Wells Fargo Technology on advancing Post Quantum Cryptography (PQC) in Transport Layer Security (TLS 1.3). Also known as Quantum TLS or QTLS, this work examined how quantum-resistant algorithms can be combined with conventional cryptographic authentication algorithms to secure future financial systems.
Quantum computing threatens RSA, DH, FFDH and ECC, which currently protect online transactions. NIST is standardizing PQC algorithms designed to withstand these attacks. The Wells Fargo and wolfSSL project tested hybrid PQC integration in TLS 1.3 to evaluate performance and interoperability while preparing for future NIST standards.
wolfSSL’s FIPS 140-3 validated cryptography library enabled hybrid key authentication that combines conventional and quantum-safe algorithms both in the X.509 certificates and TLS handshake CertificateVerify message. This approach allows financial institutions to begin migrating to PQC algorithms in a careful and conservative step-by-step approach in real environments without impacting current operations.
