Curve9767 and Fast Signature Verification

This post is about elliptic curves as they are used in cryptography, in particular for signatures. There are many ways to define specific elliptic curves that strive to offer a good balance between security and performance; here, I am talking about specific contributions of mine: a new curve definition, and some algorithmic improvements that target … Continue reading Curve9767 and Fast Signature Verification

On Linux’s Random Number Generation

I have been asked about the usefulness of security monitoring of entropy levels in the Linux kernel. This calls for some explanation of how random generation works in Linux systems. So, randomness and the Linux kernel. This is an area where there is longstanding confusion, notably among some Linux kernel developers, including Linus Torvalds himself. … Continue reading On Linux’s Random Number Generation
