Well, as if cybersecurity doesn’t have enough acronyms. There’s RIP, OSPF, TCP, IP, SSH, AES, and so many others. Now, there are three really important ones to remember: ML-KEM (Module Lattice-Based Key Encapsulation Mechanism), ML-DSA (Module Lattice-Based Signature Standard) and SLH-DSA (Stateless Hash-based Digital Signature Standard). ML-KEM is defined in the FIPS 203 standard, ML-DSA as FIPS 204, and for SLH-DSA, we have FIPS 205. https://medium.com/@billatnapier/get-used-to-three-boring-ac...

The cybersecurity world is changing, and where the signature methods of RSA, ECDSA and EdDSA are likely to be replaced by FIPS 204 (aka ML-DSA Module-Lattice-Based Digital Signature Standard— Dilithium) and FIPS 205 (aka SLH-DSA (Stateless Hash-based Digital Signature Standard — SPHINCS+) https://medium.com/@billatnapier/so-what-is-a-prehash-and-what-has-it-to-do-with-post-quantum-signatures-bf7812cfa203

In cybersecurity, there are so many acronyms, and to be an expert, you really need to dig underneath the methods and understand how they work. One weak area of the industry is in the usage of MACs (Message Authentication Codes). With the public-key signing, we use a public key and a private key, where the private key will digitally sign a hash of the message, and where the public key is verified the signature. With a MAC, we use a shared symmetric key, and where Bob and Alice will share the same...

Like it or not, AI is on the move and now competing with human brain power for its place in our world. We must thus understand the place of LLMs (Large Language Models) in areas such as cybersecurity and in planning towards hybrid systems that integrate both humans and AI within our corporate infrastructures. https://medium.com/asecuritysite-when-bob-met-alice/humans-v-ai-in-cybersecurity-52709be27111

This week, in my lecture, I will outline one of the most amazing methods ever created in computer science: the Diffie-Hellman method. It was first outlined by Whitfield Diffie and Marty Hellman in 1976 in a paper that built the foundation of our modern world of cybersecurity. https://billatnapier.medium.com/after-48-years-its-a-long-goodbye-to-the-diffie-hellman-method-a6976a562bfe...

And, so George Orwell projected a world where every single part of our lives was monitored and controlled by Big Brother. Arthur C Clark outlined the day when machines focused solely on a goal — even if it was to the detriment of human lives. And, Isaac Asimov outlined a world where machines would have to be programmed with rules so that they could not harm a human. The Rise of the Machine With the almost exponential rise in the power of AI, we are perhaps approaching a technological singularity...

Please excuse the poor quality of my microphone, as the wrong microphone was selected. In research, we are all just building on the shoulders of true giants, and there are few larger giants than Leslie Lamport — the creator of LaTeX. For me, every time I open up a LaTeX document, I think of the work he did on creating LaTeX, and which makes my research work so much more productive. If I was still stuck with Microsoft Office for research, I would spend half of my time in that horrible equation ed...

This is Day 0 of a new world of cybersecurity. Everything changes from here. There will be a time before Generative AI (GenAI) in cybersecurity and a time after it. Over the last two years, GenAI has come on leaps and bounds, and where it once suffered from hallucinations , took racist and bigoted approaches, and often was over-assertive, within ChatGPT 4.5, we see the rise of a friendly and slightly submissive agent, and that is eager to learn from us.

Whitfield Diffie is one of the greatest Computer Scientists ever. He - along with Marty Hellman - was one of the first to propose the usage of public key encryption and co-created the Diffie-Hellman (DH) key exchange method. Overall, the Diffie-Hellman method is still used in virtually every Web connection on the Internet, and has changed from using discrete log methods to elliptic curve methods. In 2015, Whitfield was also awarded the ACM Turing Prize - and which is the Nobel Prize equivalent i...
