     personally i'm saying let's go one step forward and mount the HSM onto an ultracentrifuge. if you try to slow it down, it erases itself. if you attack it mechanically and make _one single mistake_, the released energy destroys your entire lab. and maybe two or three adjacent floors

     if that's not secure enough, you could put the HSM into a gas cylinder and pressurize it to 300 bar. the tamper detection circuitry breaks off the valve

     @whitequark I believe there are military HSMs that detonate explosives if tampered with.

     @whitequark Pressurised with pure carbon monoxide. to ensure anyone trying to tamper with it is eliminated
