Re: [gentoo-catalyst] Encrypted livecd's - need testers

[Erick M]

Hi,

I'm confused about why an encrypted livecd would be an interesting feature.
Indeed if encryption is about protection, then I just see 2 ways the livecd
cd user can be attacked.
- while using the OS (real time personal information handling, like login to
gmail.com)
- after using the OS (like leaving some kind of history somewhere)

if you consider this, what is the benefit of having the OS encrypted in
memory? What kind of attack can be stopped by having encryption rather than
a clean OS?

nor differences.
>From the system point of view, as a livecd needs no HD, where would a clear
OS leave some trails or history? Can we reverse magnetic fields of RAM
devices?

I'm really interested in such topic, please could you explain some scenarios
of use/setup in which an encrypted livecd would have advantages over a
regular clear livecd?

Thanks in advance
