I've been wondering about this.. does the N900 have all enablers required to implement the Maemo 6 security framework as described in these slides http://www.slideshare.net/peterschne...tform-security ? OMAP3430 data sheet mentions ARM Trustzone support but I have way too little knowledge about security and related sw/hw to really draw any conclusions either way.

By the way, the author of those slides answered some questions about the design here http://wiki.maemo.org/MaemoSecurity
