Scientist prepares paper for CHES conference - with a little over-the-top wording in the _draft_. Paper is leaked to the internet and blown out of proportion. It's still interesting reading. Maybe Microsemi will finally listen to these guys and stop using the same password for the backdoor in _all_ of the following chips: "all ProASIC3, Igloo, Fusion and SmartFusion FPGAs" [1] Ok and PEA is just their patented method of automating differential power analysis using a test jig - it does the repetitive process using a microcontroller and some sensors instead of doing it after sampling everything with an o-scope. It's a good idea and they have worked out the fiddly little details... but a pretty simple concept. [1] http://www.cl.cam.ac.uk/%7Esps32/microsemi_re.pdf |
