Written by Cloud Security Alliance Quantum Safe Security Working Group. A mysterious paper A research paper titled “Quantum Supremacy Using a Programmable Superconducting Processor” briefly appeared last September 21, 2019 on NASA’s Technical Report Server (TRS), but was later removed.…
Regular readers of this blog will have listened to me talking about crypto-agility and quantum safety quite a bit. Quantum Safety is all about making sure that we are prepared when a quantum computers are powerful enough to be a…
What does Quantum Safety mean, how do we get there, and what does this have to do with Bitcoin? The Threat that Quantum Computers pose to Cryptography is the “killer app” for Quantum Computing. This topic strangely receives both a…
A peek at Facebook's Libra blockchain from a cryptography and quantum-safety point-of-view Facebook finally unveiled the long-rumored crypto-currency and associated blockchain Libra. While there are plenty of things to unravel (like Libra not actually being a blockchain), I wanted to…
You've heard me rambling about Quantum Computers and the impact they will have on cryptography. Probably the biggest and most well-known impact is that they will be able to use Shor's quantum algorithm to crack all RSA/ECC cryptography. Fortunately, Quantum…
The Perfect "Harvest Now - Decrypt Later" Attack In my previous article, I described how Quantum Computers threaten the foundation of current cryptographic algorithms, but critics might say that a Quantum Computer is not yet available and won't be…
Superposition, entanglement, spooky action at a distance – quantum physics is truly weird. We are surrounded by quantum devices, such as transistors inside computers and cell phones, GPS systems, medical devices etc., things that only work because they cleverly leverage…
As you may know, producing good quality random numbers is far from easy - yet they are incredibly important. Random numbers protect every cryptographic operation and many security foundations rely on random numbers being really random. But how can a…
Back in December, I had the privilege to attend my very first ever Quantum Computing conference and it will certainly be a conference that I'll never forget. Some takeaways from this conference: Quantum Computing is one of the most exciting…
The first Quantum Key Distribution (QKD) protocol was proposed in 1984, forming a very "cool" method to leverage the fundamental property of quantum nature that if you observe a system, you irreversibly change its properties. This is a fancy way…
