When I was still at university the fourth-generation programming languages were all the hype, prompting us to make jokes along the lines “fifth generation will implement do what I don’t know how”

The company 'Helium' appears to be attempting to build a national Low Power WAN (LPWAN) carrier network by asking normal people to buy and operate network nodes for them. The hotspot may be purchased directly or bundled with 3rd party IOT products and become nodes in a proprietary LPWAN that mines tokens in a blockchain.

If you’re very old (like me) you’ll likely remember the halcyon days when IP routing was not enabled by default on Cisco routers. Younger gamers may find this hard to believe, which makes it even stranger when I keep bumping into an apparently common misconception about how routers work. Let’s take a look at what I’m beefing about.
To put this in context for the younger gamers, it’s worth noting that at the time, a typical “enterprise” might be running IP, but was equally likely to run IPX, AppleTalk, DECnet or some other protocol which may – or may not – support routing. Yes, there was life before the Internet Protocol became ubiquitous. If you’re curious, the command to enable IP routing is, well:
ip routing
Guess how IPX routing was enabled:
ipx routing
Appletalk?
appletalk routing
DECnet Phase IV?
decnet [network-number] routing <decnet-address>
Ok, so the pattern isn’t entirely consistent, but it’s close enough. In one way things are much simpler now because routers tend to handle IP (and IPv6) and nothing else. On the other hand there are so many more IP-related features available, I think we should just be grateful that there’s only one Continue reading
Over the last few decades, the word ‘quantum’ has become increasingly popular. It is common to find articles, reports, and many people interested in quantum mechanics and the new capabilities and improvements it brings to the scientific community. This topic not only concerns physics, since the development of quantum mechanics impacts on several other fields such as chemistry, economics, artificial intelligence, operations research, and undoubtedly, cryptography.
This post begins a trio of blogs describing the impact of quantum computing on cryptography, and how to use stronger algorithms resistant to the power of quantum computing.
All of this is part of Cloudflare’s Crypto Week 2019, now fasten your seatbelt and get ready to make a quantum leap.
Back in 1981, Richard Feynman raised the question about what Continue reading

We live in a completely connected society. A society connected by a variety of devices: laptops, mobile phones, wearables, self-driving or self-flying things. We have standards for a common language that allows these devices to communicate with each other. This is critical for wide-scale deployment – especially in cryptography where the smallest detail has great importance.
One of the most important standards-setting organizations is the National Institute of Standards and Technology (NIST), which is hugely influential in determining which standardized cryptographic systems see worldwide adoption. At the end of 2016, NIST announced it would hold a multi-year open project with the goal of standardizing new post-quantum (PQ) cryptographic algorithms secure against both quantum and classical computers.
Many of our devices have very different requirements and capabilities, so it may not be possible to select a “one-size-fits-all” algorithm during the process. NIST mathematician, Dustin Moody, indicated that institute will likely select more than one algorithm:
“There are several systems in use that could be broken by a quantum computer - public-key encryption and digital signatures, to take two examples - and we will need different solutions for each of those systems.”
Initially, NIST selected 82 candidates for further consideration from Continue reading

As part of Crypto Week 2019, today we are proud to release the source code of a cryptographic library we’ve been working on: a collection of cryptographic primitives written in Go, called CIRCL. This library includes a set of packages that target cryptographic algorithms for post-quantum (PQ), elliptic curve cryptography, and hash functions for prime groups. Our hope is that it’s useful for a broad audience. Get ready to discover how we made CIRCL unique.
We use Go a lot at Cloudflare. It offers a good balance between ease of use and performance; the learning curve is very light, and after a short time, any programmer can get good at writing fast, lightweight backend services. And thanks to the possibility of implementing performance critical parts in Go assembly, we can try to ‘squeeze the machine’ and get every bit of performance.
Cloudflare’s cryptography team designs and maintains security-critical projects. It's not a secret that security is hard. That's why, we are introducing the Cloudflare Interoperable Reusable Cryptographic Library - CIRCL. There are multiple goals behind CIRCL. First, we want to concentrate our efforts to implement cryptographic primitives in a single place. This makes it easier Continue reading
