Creating a CTF for your students, pupils or employees? Here are hundreds of CTF generators, and each is uniquely generated ... asecuritysite.com/ctf/

OpenSSH supports the SSH protocol, which allows for remote login. One tool it uses is ssh-keygen, which allows for the generation of RSA and elliptic-curve keys. These can be used for user and host authentication, such as for GitHub & Cloud instance login. asecuritysite.com/openssh/

Zero Knowledge Proofs with Elliptic Curves and Schnorr. With Zero Knowledge Proofs (ZKPs), Peggy can have a signature, and then use this to prove that she still knows her secret. The method we will use is based on Schnorr’s protocol. View more: asecuritysite.com/zero/zkhmac

I enjoyed presenting at #LTDH on Saturday ...

18 months ago NIST suddenly switched to counting memory-access costs in lattice attacks, massively pumping up Kyber-512's claimed security level. New lattice-attack optimization from Zhao, Ding, and Yang makes the memory-access costs practically disappear: eprint.iacr.org/2024/739

For Tahir Elgamal's PhD, he created the ElGamal encryption and signature method. Overall, ElGamal is a public key encryption method, and which has a public key (P,G,Y) and a private key (x). ElGamal for a key of a given bit length: asecuritysite.com/elgamal/elgama…

In full disk encryption, we cannot add an IV (Initialization Vector), as we often will want to access specific sectors and blocks without having to read all of the sectors. Here is XTS: asecuritysite.com/golang/go_xts

Big highlight of this academic year was when Whitfield Diffie came along to speak with our students. But for me, it was just as great as when the mighty Daniel J. Bernstein was our guest. Creator of Curve 25519, ChaCha20, and SipHash.

Our ctf is about to start for #ltdh24 day 2. May the best team win!

Thank you again to ZeroDays CTF for sponsoring our ctf this year.

Imagine bragging about how the government can both track you and control your money ......

This isn't a flex.

Opening keynote from our very own Prof B Buchanan OBE FRSE scaring us with AI current research and tools … citing the daily star … and where we might end up … #killswitchjobs

How Do I Get Into Cryptography? Almost every day I get asked about how someone can get into cryptography. Well, it can take a while to develop a deep understanding, but here’s my tips:

Would your company sign up to these seven cybersecurity pledges?

Multi-factor authentication (MFA).
Default passwords
Reducing entire classes of vulnerability.
Security patches.
Vulnerability disclosure policy.
CVEs.
Evidence of intrusions.

At Le Tour Du Hack… It was nice meeting Bill Buchanan in person. He is a legend in Cybersecurity and happens to be a former student of Graeme High School. Here he is with current students of Graeme.

Security BSides Dublin Grigorios Fragkos Meanwhile at LeTour, we have Prof B Buchanan OBE FRSE talking about AI, deep fakes, and the future of these technologies

Good to catch up with Rich Macfarlane one of the founders of ENUSEC

Honoured to be trusted to give a keynote for the mighty #LTDH24 conference
