Scouting report
Co-authored the cold boot attack paper showing DRAM retains keys after power off, then spent a career demonstrating — in court and in front of legislatures — that deployed voting machines could be reprogrammed. Co-founded the Internet Security Research Group behind Let’s Encrypt, and co-authored the ZMap internet-wide scanner and the Logjam and FREAK results.
Curator’s note
Let’s Encrypt alone changed the default state of the web from plaintext to TLS.
