The world is adopting anonymous credentials for digital privacy, but these systems are vulnerable to quantum computers. This post explores the cryptographic challenges and promising research paths toward building new, quantum-resistant credentials from the ground up.
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.
One way that attackers DDoS websites is by repeatedly doing DNS lookups that have small queries, but large answers. The attackers spoof their IP address so that the DNS answers are sent to the server they are attacking, this is called a reflection attack.
It is no secret that we at CloudFlare love Go. We use it, and we use it a LOT. There are many things to love about Go, but what I personally find appealing is the ability to write assembly code!
The newly announced FREAK vulnerability is not a concern for CloudFlare's SSL customers. We do not support 'export grade' cryptography (which, by its nature, is weak) and we upgraded to the non-vulnerable version of OpenSSL the day it was released in early January.
This blog post is dedicated to the memory of Dr. Scott Vanstone, popularizer of elliptic curve cryptography and inventor of the ECDSA algorithm. He passed away on March 2, 2014.
