Completely false. Hardware key loggers in the PC could be storing the
data anywhere. Also, if the data came from the internet, it could
have been recorded in transit, say at whatever router or firewall the
PC is connected to the net through. The same goes if you did
something with the PC like send private email. If you think that
running Linux from a USB drive on a public PC (airport kiosk or
whatever) is going to make your usage private, think again.
This is right of cause.
What I also like is that it is now easier to access the data on that
PC you stick the USB-stick in, as you can bypass any passwords,
just mount any drive, and get the whole directories you are
interested in, take it home and decrypt there if needed.
But from a point of view of virus free booting, not bad is it?
Oh I am sure there are ways around that too, as is around anything.
And I like to have a Linux with me that I can run on almost any PC,
such a mem stick is a lot better then carrying a laptop...
Not to mention file transfer to / from the host.
The other thing is that a 'hardware key logger' would have to run
on its own processor and monitor the USB bus, as the main processor will
be running Linux, no way it will run something else at the same time.
A device in the keyboard, OK.
But then all bets are off.
The network is exactly what is avoided if you transfer to-from the stick
from a resident disk.
Finally you could encrypt the data on the stick itself with some algo and key
(you needed to enter for it to boot), so even then if it is robbed it would
be of no use.
Pros and contras, but it adds an other dimension, uses its pros.
If you like, I sure will, as I am experimenting with this. |

No
you have no clue right?
OF CAUSE win whatever does not fit in 64 MB
That is why you should not buy it.
Really? I mean my laptops 60GB disk would be fairly empty if I ran my OS
off a flash drive....
Ah, probably full of crap anyways
No it full of a complete copy of MikTeX, Cygwin, 14GB of mp3s, OpenOffice,
many NES/SNES/GBA/GB games [and other games], Maple and a variety of other
applications.
See, unlike you I actually do real work with my computer instead of just
rambling in usenet about the latest cool think you read up from BYTE
magazine or whatever..A flash drive would not cut it for me. For starters
they're too small. Second development uses a lot of memory + temp files.
Unless I set aside some dedicated ram drive [not willing todo] I'm going to
kill the flash drive wickedly quick.

Hi, well, do not take it personal, although you calling me a troll did reduce
my politicalness a bit.
So 'crap'.
If you are looking at actual work, well I put more source under the GPL then
you, and do not moan about licenses, I know some it it is now in commercial
stuff.
Games, well, I have 80 MB and it is a transient for mpeg2 satellite
recording.
Without the 2 GB at a time files there would be a lot of open space.
All the 'work' I did in the last 30 years (source written) will fit on a
flash drive (512 MB is available).
Remove all those object files and executables, just the source.
This is the amazing thing about fash memory / chips as memory.
And the edited video goes on DVD masters and leaves the drive to HAVE that
space.
I stopped reading Byte 10 years ago, as I stopped reading most of the crap in
the book shops these days.
Only thing I buy on occasion is C'T and I think in US / America there is
nothing like it.
But I have not looked.
C'T had the Knoppix 3.3 CD with it.
Absolutely a good rescue disk.
In the video world we will see Flash memory in video cameras replace other
(mechanical) media, the advantages like shock resistance and power
consumption and size are very big.
If MRAM or the likes makes its way, we will see more solid state.
The flash 128MB I have here now has less then 20 MB or so Linux 2.4 kernel on
it now.
It can be used for other things too, like access control etc...
Since you are just a soft writer, and only in a very small sub aspect of it,
and have no clue about the electronics involved I would shut up
if I were you because I know both professionally.
You fail the imagination and experience to combine the fields, and are blind
for what can be done, even if the equipment was in your hands.
Keep working on it. |

Seems to me another poster tore you to shreds already. A flash based OS is
only as secure as the computer you put it in. So really there is little
value to it. Note that some embedded systems come with their own flash for
the OS, this isn't becauseflash is so much secure it's because it's
re-writeable, no moving parts and relatively low power.
As one great /. poster put it.
You failed at the internet.

Get some electronics education, you did not understand a word I said.
Design a computer, get a feel, write an OS, get a clue.
I have all that.
You did not even fail, you did not even start 
Hey Tom, Happy Newyear!
Only ONE great poster? WOW, and that was YOU?
FWIIW
Problem with you software kids is that you dunno a thing about how
the hardware works, and because of that are for ever imprisoned in
your concept of it. |

Um you don't need EE to understand this thread.

I've build computers before. Haven't written an OS but I don't see what
this has todo with the thread.
Ok.
Quote: You did not even fail, you did not even start
Ok.
Quote: Hey Tom, Happy Newyear!
You're late with this one. I go by the new calendar so my new years was Jan
1st [not Jan 7th as my mother would have it ...  ]
Quote: Only ONE great poster? WOW, and that was YOU?
Um, no. It was another sci.crypt poster who tore you to shreds. Maybe you
ought to carefully read all of the replies you get.

Ok so I design a computer with loggers-galore in it. You put your flash
drive in it. How is this secure?
Anyways, you're right, I'm wrong. Don't bother replying since I'll just
concede you're right.
