How Verizon and a BGP Optimizer Knocked Large Parts of the Internet Offline Today

Massive route leak impacts major parts of the Internet, including Cloudflare What happened? Today at 10:30UTC, the Internet had a small heart attack. A small company in Northern Pennsylvania became a preferred path of many Internet routes through Verizon (AS701), a major Internet transit provider. This was the equivalent of Waze routing an entire freeway down a neighborhood street — resulting in many websites on Cloudflare, and many other providers, to be unavailable from large parts of the Internet. This…

Introducing time.cloudflare.com

This is a guest post by Aanchal Malhotra, a Graduate Research Assistant at Boston University and former Cloudflare intern on the Cryptography team. Cloudflare has always been a leader in deploying secure versions of insecure Internet protocols and making them available for free for anyone to use. In 2014, we launched one of the world’s first free, secure HTTPS service (Universal SSL) to go along with our existing free HTTP plan. When we launched the 1.1.1.1 DNS resolver, we also…

Top 5 Skill Building Community Every Programmer Needs To Follow

When someone hears the word ‘programmer’, all they imagine is a super-smart guy who can hack into any alien system in the world, which is far from reality. I mean sure, they can hack into an alien system from any galaxy but being the smartest will not always help. Anyone can be a programmer but being a programmer takes years of effort and hard work. The learning should be dynamic and constant because how else will you stay up-to-date with…

The Quantum Menace

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…

Introducing CIRCL: An Advanced Cryptographic Library

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. Cryptography in Go We use…

Sensors and metrology as the driving force for digitalization

Credit: CC0 Public Domain Many digitalized processes depend on data collected by increasingly powerful sensors and other test and measurement technology. When this data is processed, it provides precise and reliable information about the operating environment. Nine Fraunhofer Institutes will be presenting the results of their research into sensor technology and its applications in the field of testing and measurement at Sensor+Test 2019 in Nürnberg from June 25 to 27 (Booth 248 in Hall 5). A great many innovations in…

Dangerous brain parasite ‘orders in’ for dinner — ScienceDaily

Researchers at Indiana University School of Medicine have discovered how a dangerous parasite maintains a steady supply of nutrients while replicating inside of its host cell: it calls for delivery. Toxoplasma gondii is a single-celled parasite capable of infecting any animal, including humans. Up to one-third of infections in people happen through contact with cat waste or contaminated food or water. Although the parasite only causes acute disease in immune compromised persons, the infection is permanent and has been associated…

Most Fascinating Future Technological Projects

The 21st century is a prolific period for advanced technological projects. Mobile phones morphed into pocket personal computers. Internet connection unites professionals all over the world. Machine learning and virtual reality monopolized the entertainment world. Modern medical equipment helps patients recover from, previously, incurable diseases. This list can be continued with hundreds of new inventions that already exist. But what innovations wait for people in the future? Inventions Coming Before 2100 Mary Hampton, a private essay writer, notes that writing…

What is a Virtual Private Network or VPN?

Virtual Private Network or VPN is a program which allows users to create a secure connection to another network over the internet. It creates a safe connection over a less secure network, such as the public internet. It works by utilizing security procedures and tunneling protocols. Simply put, a VPN creates a virtual encrypted tunnel between the user and a remote server operated by a VPN service. In thus creating, all internet traffic is routed through this tunnel, so the…

Security Compliance at Cloudflare

Cloudflare believes trust is fundamental to helping build a better Internet. One way Cloudflare is helping our customers earn their users’ trust is through industry standard security compliance certifications and regulations. Security compliance certifications are reports created by independent, third-party auditors that validate  and document a company’s commitment to security. These external auditors will conduct a rigorous review of a company’s technical environment and evaluate whether or not there are thorough controls – or safeguards – in place to protect…
