Scouting report
Co-authored “Mining Your Ps and Qs”, which scanned the whole IPv4 internet and found that a meaningful share of TLS and SSH keys shared factors because embedded devices generated them without entropy — and then factored them. Followed it with Logjam, DROWN and FREAK, a body of work whose method is: measure what is actually deployed, then break the weak part.
Curator’s note
Proved the crypto was fine and the random number generators were not.
