In my “Dangers of a Cashless Society” post, I briefly described my experiences in Sweden. This post expands on that.
Read article: Sweden’s Cashless Revolution: The Hidden Costs of a Digital EconomyQuick Summary: AES-256 is the workhorse of enterprise data encryption at rest. It is not considered impacted by quantum computers or Post-Quantum Cryptography. It is considered quantum-resistant, which means it can withstand attacks from quantum computers / algorithms better than other encryption…
Read article: AES-256 and the Post-Quantum Panic: The Rare Cryptographic Algorithm That Isn’t SweatingFor decades, modern cryptography has rested on a comforting assumption that factoring really large numbers is hard.
Read article: Shor’s Algorithm: The Quantum Computer’s Favorite Way to Ruin RSA’s DayML-KEM (Module-Lattice-Based Key Encapsulation Mechanism), formerly known as CRYSTALS-Kyber, is the post-quantum key exchange algorithm standardized by National Institute of Standards and Technology as FIPS 203. Its security is based on the difficulty of certain problems in lattice cryptography,…
Read article: Post-Quantum Cryptography (ML-KEM): The MathFor decades, modern cybersecurity has relied on a handful of cryptographic foundations. Technologies such as RSA and Elliptic Curve Cryptography (ECC) protect everything from online banking and VPNs to software updates and digital signatures. These algorithms have withstood years of scrutiny and…
Read article: Post-Quantum Cryptography (2026): Preparing for the End of RSA and ECCMost people use cryptography every day. They log into websites. They check their bank balances. They send messages. They order things they absolutely do not need from online retailers at 2:00 AM.
Read article: RSA: The Internet’s Favorite Math Trick (Until Quantum Computers Show Up)Disclaimer: I’m not a physicist. This is my attempt to understand quantum computing and the underlying physics, yet keeping it light. I do actually want my traditional audience to read this.
Read article: Introduction To Quantum Computing: Because Regular Computers Apparently Weren’t Complicated EnoughThis is the fifth (and final) post in my “AI / LLM Software Security Series”.
Read article: AI / LLM Software Security: Part 5This is the forth post in my “AI / LLM Software Security Series”.
Read article: AI / LLM Software Security: Part 4When I was writing the Zero Knowledge Proofs: The Math blog post, I had the bright (read stupid) idea of asking ChatGPT to generate an image about math. It didn’t matter which math, didn’t specifically mention ZPTs in the prompt. It initially generated the above image. It’s a good image. It’s the…
