I have four major presentations coming up over the next few weeks. And the topic? Quantum computers: their risks and benefits. One of the greatest changes in cybersecurity is underway. Some companies will immediately move, some will wait, and then others may not change over at all. What’s the change…

The future of cybersecurity is data and machine learning — I am sad to see Cisco’s take-over of Splunk — but I suppose it’s all part of business. Two of our spin-outs were acquired by large companies, and those who invested in them received a reward for their investment. The funds generated will hopefully be re-invested into new businesses, and…

Small keys and a relatively large signature — Ad so NIST has set up Round 1 of the Additional Signatures for PQCs [here]. These are grouped as follows: Multivariate Signatures (10): 3WISE, DME-Sign, HPPC (Hidden Product of Polynomial Composition), MAYO, PROV (PRovable unbalanced Oil and Vinegar), QR-UOV, SNOVA, TUOV (Triangular Unbalanced Oil and Vinegar), UOV (Unbalanced Oil and…

Cisco perhaps missed the rise in cybersecurity, but they are now a strong contender. But, it was Splunk who saw the greatest opportunity. Now, Cisco is to acquire Splunk for $28 billion, and is the end of a journey for Splunk, and where they completely disrupted the world of cybersecurity…

As an academic, I get the privilege to see the “start” (The Open Day) and “end” (the graduation) of someone’s route through Higher Education. I try never to miss these. In between, I see students flourish and, hopefully, achieve their full potential. For our undergraduates, this can be four years…

Here’s my 6 am doodles from this morning on multivariate cryptography:

If you are into cybersecurity, then you will know all about the MD5 hashing method. But do you know what the MD part represents? Well, it could be Message Digest, but it could also be the Merkle-Damgård (MD) construct on which MD5, SHA-1 and SHA-2 are built upon. Overall Ivan…

If you are into cybersecurity, you should know all about the birthday attack, as it is a typical model used to estimate how quickly a hash value can be cracked. The theory goes that in a room of 23 people, there will be a 50% chance of at least two…

I find these tables rather silly:
