Harvest Now, Decrypt Later (HNDL) Risk
"Harvest Now, Decrypt Later" (HNDL), also known as "Store Now, Decrypt Later" (SNDL), is a concerning risk where adversaries collect encrypted data with the intent to decrypt it once quantum computing becomes capable of breaking current encryption methods. This is…

A (Very) Brief History of AI
As early as the mid-19th century, Charles Babbage and Ada Lovelace created the Analytical Engine, a mechanical general-purpose computer. Lovelace is often credited with the idea of a machine that could manipulate symbols in accordance with rules and that it…

When ML Bias Becomes a Security Failure
A demographic differential in false match rate is a demographic differential in exposure to impostors. NIST measured it in 2019 and called it a security concern. The security profession has spent nearly seven years reading the other error rate.

Quantum Errors and Quantum Error Correction (QEC) Methods
Quantum error correction (QEC) is therefore critical for enabling large-scale or fault-tolerant quantum computing. Fault tolerance means a quantum computer can continue to operate correctly even when individual operations or qubits error out. Unlike classical error correction – which can…

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…
