As secure as rock, paper, scissors at once – Art of Defence, Demo at DEFCON

A team of great people from the Security Group at UCL and our start-up Enigma Bridge designed and implemented a practical security system tolerant to severe attacks compromising all parts of the supply chain. We will present and demonstrate it at DEFCON in Las Vegas.

The potential of multi-party signing – as secure as its STRONGEST link

Is it really possible to design an encryption system, which is as strong as its strongest link? There is never a straight “yes” answer to this question, but we are now as close as one can get.

Guardian, FT, etc. share their internet encryption keys with many

We have all heard about hackers stealing huge user databases with passwords as they are tempting bounties. FT, Guardian and many others create a new kind of reward – their internet encryption keys via CDNs – services speeding up web traffic.

SSL testing – servers or domains?

We have started testing our SSL certificate spot checks – KeyChest – and realized that we were conceptually different from SSL Labs. We focus on the server rather than the domain name and it makes a difference.

SSL certificates – 7 Free Spot Checks in one go – KeyChest

While implementing features of the certificate planner, we have added a few handy features to the KeyChest spot checker as well. It is now much more than just a tool to check when a website certificate expires.

First BlackHat, now DEFCON: We talk “Trojan-tolerant hardware security in practice”

I have mentioned this multi-party encryption project of ours (Enigma Bridge) and University College London here earlier. If you’re planning to go to BlackHat US or DEFCON-25, come and see our talks about practical “ultra-secure” multi-party encryption for the cloud and some of the technology enabling it (Unchaining the JavaCard Ecosystem).

Meet your internet neighbors – sharing SSL keys with strangers

You may think I’m pulling your leg, when I say that you share encryption keys with an adult content website, road sweepers West Sussex, or hackers trying to impersonate Apple. But that’s exactly what happens when you use a free (CDN) service with HTTPS.

Black Hat 2017 USA – OpenCrypto: Unchaining the JavaCard Ecosystem

We have been working with University College London (UCL) for a while and one of the results is an easy to use implementation of cryptographic functions for JavaCards. We will be briefing on this at Black Hat 2017 USA.

Do you have screenshots of your crypto platform?

We basically gave up on going to startup events for now. I know It’s not good for marketing or when you look for equity investment. We just got tired of trying to explain what a “platform” is good for. Everyone expects a flashy demo or screenshot of your app.

Does Amazon Want To Control All Encryption Keys?

Public cloud providers have absolute control over our data, applications, everything we do on their cloud platform. Independent key management lowers users’ risk exposure and as such is in the interest of cloud providers. Well, Amazon AWS has different thoughts.
