True HSM with active self destruct needs to be constantly powered. On the other hand for many if not most applications, typical secure smart-card is is completely sufficient (and in fact typical POS card terminal stores most of it's long term secrets on SIM-like smart-card).
- numpad0 7y agoSomewhere in my junk parts bin is such a PCI card I bought out of a junk bin at Akihabara, that has Mitsubishi logo clearly printed with archaic construction overall, apparently marketed by NEC somehow, which product brochure page disappeared after I mentioned it on Twitter, Had a pair of blown AA battery for self destruction. I never bothered to get it working, but IIRC it was supposed to detect removal from PCI slot(the proper) to self erase. So it’s not rare or difficult.
