Re: Is There a Visor Security Model?
The Palm's security model is, by most accounts I've seen, non-existant. The issue is the lack of memory protection, i.e., that there is no protected space for keying material. Visor is said to use the PalmOS as is, so that is not a magic wand. Of course, if your OS has no memory protection, you can always rely on yet another external hardware device, as has already been mentioned. --dan

IIRC, the SDK has the src for all of the builtin apps, so gaining that trust should, at least, only be a matter of work, not of negotiation. - -JimC - -- James H.

Is There a Visor Security Model?
Everyone's probably heard of the new Palm-alike Visor by now, and it's got this "springboard" slot in the back processors, memory, and other stuff. The Palm's security model is, by most accounts I've seen, non-existant. Is the Visor any better? It would be nice to have a portable cryptographic/signature/digital money device. Are we any closer?

Even if a "springboard" module doesn't come out, it's got USB, which can be used with the ikey's for key storage and some crypto. That's an improvement. http://ikey.rainbow.com/ (if it's new to you).

RE: Is There a Visor Security Model?
The Visor uses Palm OS, so I don't think it's any better.
