Inside NIST’s PQC: Kyber, Dilithium, and SPHINCS+
In 2022, after a multi-year evaluation, NIST selected CRYSTALS-Kyber, CRYSTALS-Dilithium, and SPHINCS+ as the first algorithms for standardization in public-key encryption (key encapsulation) and digital signatures. Kyber is an encryption/key-establishment scheme (a Key Encapsulation Mechanism, KEM) based on lattice problems,…

Adversarial Attacks on AI: What Has Actually Been Demonstrated
Adversarial examples are a real and unsolved property of trained models. Almost every famous demonstration of one attacking a deployed system is weaker than the headline it produced, and the gap between those two facts is where defensive practice goes…

Gradient-Based Attacks: Which Gradient, and Where It Stops Working
In the continuous case the gradient hands you the attack. Everywhere else it only ranks candidates, and something slower does the actual work. That gap explains why these methods dominate image benchmarks and underperform in the places security teams care…
