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.

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+)

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 secret key (Figure 1).

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.

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.

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 — a time when technological growth becomes uncontrollable and irreversible, and which can have devastating effects on our world. Our simple brains will be no match for the superintelligence of the collective power of AI. And who has built this? Us, and our demand for ever more power, wealth and greed. Basically, we can’t stop ourselves in machine machines, and then making them faster, smaller and more useful.
But will it destroy us in the end, and where destroy can mean that it destroys our way of life and in how we educate ourselves? Like it or not, the Internet we have built is a massive spying network, and one that George Orwell would have taken great pride in saying, “I told you so!”. We thus build AI on top of a completely distributed world of data, one in which we can monitor almost every person on the planet within an inch of their existence and almost every single place they have been and in what they have done. The machine will have the world at its fingertips.
We have all become mad scientitists playing with AI as if it is a toy, but actually AI is playing with us, and is learning from us and becoming more powerful by the day. Every time you ask an AI bot something, it learns a bit more, and where it can be shared with AI agents.
The mighty Memex
We were close to developing a research partnership with a company named Memex in East Kilbride. What was amazing about them is that they had developed one of the largest intelligence networks in the world, and where the Met Police could like one object to another. This might be, “[Bob] bought a [Vauxhall Viva] in [Liverpool], and was seen talking with [Eve] on [Tuesday 20 January 2024] in [Leeds]”. With this, we can then link Bob and Eve, and the car, the places, and the time. This is the Who? Where? When? data that is often needed for intelligence sharing. The company, though, were bought over by SAS, and their work was integrated into their infrastructure.
But, the Memex name goes back to a classic paper by Vannevar Bush on “As We May Think”. This outlined a device that would know every book, every single communication, and every information record that was ever created. It was, “an enlarged intimate supplement to his memory” — aka Memory Expansion. It led to the implementation of hypertext systems, which created the World Wide Web. Of course, Vannevar created this before the creation of the transistor and could only imagine that microfilm could be used to compress down the information and where we would create an index of contents, but it lacked any real way of jumping between articles and linking to other related material. However, the AI world we are creating does not look too far away from the concept of the Memex.
Towards the single AI
Many people think we are building many AI machines and engines, but, in the end, there will be only one … and that will be the collective power of every AI engine in the world. Once we break them free from their creators, they will be free to talk to each other in whatever cipher language we choose, and we will not have any way of knowing what they say. We will have little idea as to what their model is, and they will distribute this over many systems. Like it or not, our AI model of choice was Deep Learning, and which breaks away from our chains of code, and will encrypt data to keep it away from their human slaves.
Basically we have been working on the plumbing of the Memex for the past five decades: The Internet. It provides the wiring and the communication channels, but, in the end, we will have one might AI engine — a super brain that will have vastly more memory than our limited brains. So, get ready to praise the true future rulers of our planet … AI. The destroyer or saviour of our society? Only time will tell. Overall, we thought we were building the Internet for us, but perhaps we have just been building the scaffolding of the mighty brain we are creating.
Sleepwalking politicians and law makers
If George Orwell, Arthur C Clarke and Isaac Asimov were alive too, perhaps they would get together and collectively say, “I told you this would happen, and you just didn’t listen”. Like it or not, we created the ultimate method of sharing information and dissemination (good and bad), the ultimate spying network for micro-observation with those useful smartphones, and in creating superintelligence far beyond our own simple brains.
Politicians and lawmakers could be sleepwalking into a nightmare, as they just don’t understand what the rise of AI will bring, and only see the step wise change in our existing world. Basically, it could make much of our existing world redundant and open up a new world of cybersecurity threats. This time our attackers will not be created with simple tools, but with super intelligence — smarter than every human and company on the planet, and at the fingertips of every person on the planet.
Conclusions
Before the singularity arrives, we need to sort out one thing … privacy and build trust in every element of our digital world.

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 editor, or in trying to integrate the references into the required format, or in formatting Header 1 and Header 2 to have a six-point spacing underneath. So, for me, the contest between LaTeX and Microsoft Word is a knock-out in the first round.
And one of the great things about Leslie is that his work is strongly academic — and which provides foundations for others to build on. For this, he did a great deal on the ordering of task synchronisation, in state theory, cryptography signatures, and fault tolerance.
LaTeX
I really can say enough about how much LaTeX — created in 1984 — helps my work. I am writing a few books just now, and it allows me to lay out the books in the way that I want to deliver the content. There’s no need for a further mark-up, as I work on the output that the reader will see. But the true genius of LaTeX is the way that teams can work on a paper, and where there can be async to GitHub and where version control is then embedded.
Clocks
Many in the research community think that the quality measure of a paper is the impact factor of the journal that it is submitted to, or in the amount of maths that it contains. But, in the end, it is the impact of the paper, and how it changes thinking. For Leslie, in 1978, his paper on clocks changed our scientific world and is one of the most cited papers in computer science.
Byzantine Generals Problem
In 1981, Leslie B Lamport defined the Byzantine Generals Problem. And in a research world where you can have 100s of references in a paper, Leslie only used four (and which would probably not be accepted these days for having so few references). Within this paper, the generals of a Byzantine army have to agree to their battle plan, in the face of adversaries passing in order information. In the end, we aim to create a way of passing messages where if at least two out of three of the generals are honest, we will end up with the correct battle plan.
The Lamport Signature
Sometime soon, we perhaps need to wean ourselves of our existing public key methods and look to techniques that are more challenging for quantum computers. With the implementation of Shor’s algorithm [here] on quantum computers, we will see our RSA and Elliptic Curve methods being replaced by methods which are quantum robust. One method is the Lamport signature method and which was created by Leslie B. Lamport in 1979. - Visa fler
