Clifford Cocks is a British mathematician and cryptographer. While working at GCHQ, he invented public key encryption, and which predates the work of the RSA and Diffie-Hellman methods. He studied mathematics as an undergraduate at Kings College, Cambridge, and then joined the Communications-Electronics Security Group (CESG) at GCHQ in 1973. After his discovery of a usable public key encryption method, he went on to create one of the first Identity-Based Encryption methods and which is based on quadratic residues rather than bilinear pairings.
In 2008, he was made a Companion of the Order of the Bath (CB). Then, in 2010, he and James Ellis and Malcolm Williamson were honoured by the IEEE for their part in the development of public key encryption. In 2015, he was elected as a Fellow of the Royal Society, and, in the same year, he received an honorary PhD from the University of Birmingham. Then, in 2021, Clifford was inducted into the Cryptologic Hall of Honour.

Vadim Lyubashevsky is a cryptographer at IBM Research Europe in Zurich. He received his PhD from the University of California, San Diego in 2008. His core research focus is around lattice-based methods, and especially in areas of practical lattice encryption, digital signatures and privacy-preserving primitives. Along with Chris Peiker and Oded Regev (the inventor of LWE), he published a classic paper entitled "On ideal lattices and learning with errors over rings", which has been used as a foundation for lattice methods within post-quantum cryptography. Vadim has worked in many areas of cryptography, including Zero Knowledge Proofs, Blind Signatures and Multiparty Computation.

Alfred Menezes is a Professor at the University of Waterloo in Ontario. In 2001, he won the Hall Medal from the Institute of Combinatorics and its Applications. Alfred is the lead author of the Handbook of Applied Cryptography, and which has been cited over 25,000 times. He has published many high impact papers, especially in areas of public key encryption and elliptic curve cryptography, and was the co-inventor of the ECDSA signature method.
His website for online courses is https://cryptography101.ca. The "Cryptography101: Building Blocks" and "Cryptography 101: Deployments" courses are lectures from the undergraduate "Applied Cryptography" that he has taught at Waterloo since 2000. The former includes a five-lecture introduction to elliptic curve cryptography. He also has a course on "Kyber and Dilithium", and soon an intro to "Lattice-based cryptography".

This seminar series runs for students on the Network Security and Cryptography module, but invites guests to participate. Bruce has created a wide range of cryptographic methods including Skein (hash function), Helix (stream cipher), Fortuna (random number generator), and Blowfish/Twofish/Threefish (block ciphers).
Bruce has published 14 books, including best-sellers such as Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World. He has also published hundreds of articles, essays, and academic papers. Currently, Bruce is a fellow at the Berkman Center for Internet and Society at Harvard University.

Brent Waters is a Professor at the University of Texas at Austin and the Director of the Cryptography Lab at NTT Research. He graduated from the UCL in 2000, then completed a PhD at Princeton University in 2004. After this, he moved on to Stanford as a postdoc.
Overall, Brent was the first to propose Attribute-based Encryption (ABE) and also the first to outline functional encryption. He was also awarded the Sloan Research Fellowship in 2010, and, in 2015, he was awarded the Grace Murray Hopper Award for his work on ABE and functional encryption.
Brent’s research has been cited over 68,700 times for his research work, and has provided a core foundation for cybersecurity to move towards methods that provide fine-grained data access.

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.
