Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

Here we go posted August 2013

Bordeaux

Hey guys, I'm David Wong, a 24 years old french dude who's going to start a Master of Cryptology in the university of Bordeaux 1.

Cryptology (or as Americans like to call it: Cryptography, because we all know they don't care about etymology) is the study of the techniques for secure communications (thanks Wikipedia!), from withdrawing money with a fake credit card to establishing a safe phone conversation between two government officials, it can mean a lot of things... I still have no clue what my future job will be, that's why I had the idea of making this small blog where I could post about my ventures into this new world and, hopefully, being able to take a step back and see what I did, what I liked, what happened in two years of Master (and maybe more).

I've already took Cryptography I given by Dan Boneh from Stanford and I must say I really enjoyed going through his course. Might be one of the most interesting and eloquent teacher I had in my life, and I have never met him. Had a few back and forth mail exchanges with him but sadly, there was no collaboration between our universities. California I'll see you later in life I guess.

I'll also post some thoughts about the new city I'll be moving to : Bordeaux. This is for at least 2 years, or less if I change my mind. Anyway, this is going to be exciting!

Well done! You've reached the end of my post. Now you can leave a comment or read something else.

Is this blog about cryptozoology and cryptogram as well? That would be cool! =D

PS : one tenth design/coded by David Wong, nine tenth design/coded by Bootstrap =p

> Cryptozoology is a pseudoscience involving the search for animals whose existence has not been proven.

What???

And yeah most of the job was done by Bootstrap... and CodeIgniter as well :)

Pas nécessaire. Je pense pas qu'il y aura énormément de commentaires/traffic, et je me dis que si ça devenait un problème plus tard je patcherais le truc. J'ai codé le site en 2 heures donc j'ai prit beaucoup de raccourcis =)

David,
Thank you so much for writing Real World Cryptography. I've been listening to the audiobook every night while I'm in Sec+ boot camp and I just bought the kindle version. There's just so much I don't think I can absorb it without going multimodal so I'm going to increase brain blood flow by walking on a treadmill with the kindle in front of me and follow along on the text while listening to the audiobook. Research says it helps and it certainly helped me during Constitutional Law when I had to read The Federalist Papers.
Thank you SO much for writing THE quintessential book on cryptology. Uh, I mean cryptography as my fellow Americans say.
Best Regards,
Charlie
