As quantum computing advances threaten current encryption standards, Cryptography 101 announces a comprehensive course series on post-quantum cryptography. The curriculum covers lattice-based algorithms, hash signatures, and cryptanalysis tools critical for future-proofing digital security. Starting August 2024, these courses address urgent industry needs for quantum-resistant expertise.

Kudelski Security engineers have engineered two novel approaches to fortify WireGuard against quantum attacks—one optimizing for speed using a modified Kyber KEM, the other slashing bandwidth via Rainbow signatures. Their open-source fork achieves handshakes under 5ms while halving packet overhead, proving practical post-quantum VPNs are within reach.

As the tech industry races to deploy post-quantum cryptography (PQC) against future quantum attacks, a high-stakes standards war is raging in the IETF. The NSA and GCHQ are advocating for 'pure' PQC encryption in TLS 1.3, stripping away the proven safety net of traditional elliptic-curve cryptography (ECC)—despite breaches like SIKE proving hybrid ECC+PQC is critical. This article exposes how regulatory pressure and flawed consensus threaten to normalize reckless security practices.

Discover the cryptographic ingenuity behind SARE—a hybrid post-quantum encryption project that uses a 128-byte master seed to derive all keys, merging classical and quantum-resistant algorithms. Learn how this approach simplifies key management while offering unprecedented brute-force resistance.

Quantum computers threaten to shatter the foundation of modern encryption, putting global data security at risk. With 'harvest now, decrypt later' attacks already underway, the race for quantum-resistant algorithms has become critical infrastructure's most urgent challenge. This deep dive explores why developers and enterprises must start their cryptographic migration years before quantum supremacy arrives.

Researchers have developed a novel lattice-based homomorphic encryption scheme enabling secure, private execution of quantum programs on potentially untrusted quantum hardware. The approach, using Module Learning-With-Errors (MLWE) and innovative 'bounded natural super functors', promises practical performance compatible with near-term quantum clouds while defending against quantum attacks. Crucially, it tackles previously overlooked practical challenges like handling encrypted measurements and circuit privacy.
