My MiniLock Concerns

Or on the cyber-playing field

Disclaimer: Some of my concerns and proposed changes may be addressed and included into the miniLock code before the official release, greatly improving security. I will post a new entry once the merge has happened to describe the changes and how they make miniLock much more secure. Until then, please take the below with a large grain of salt . . .

Towards a new model of computational expressiveness

Since joining the cult of LangSec, I've spent a great deal of time pondering what makes a programming language or environment "useful" and believe that the current model centered around Turing-completeness is no longer sufficient to describe the nuances between varied environments.

LANGSEC: Taming the Weird Machines


I want to get some of my opinions on the current state of computer security out there, but first I want to highlight some of the most exciting, and in my views, promising recent developments in security: language-theoretic security (LangSec). Feel free to skip the next few paragraphs of background if you are familiar . . .

Welcome to Security Counterpoint

Hello and welcome! This is the home of Jacob's musings on security, a place I can edify, extrapolate and explore current happenings in information security. I am a senior security research engineer (though all opinions are my own) where I lead a team focusing on low-level (e.g. BIOS/SMM/VMM) security at the architectural level; I also . . .
