Re: Sealing wax & eKeyboard(Tempest for eliza)

hi,

We can give a tempest demo just with a radio .There is
a fun project called tempest for eliza which gives an
insight of the computer security.


Tempest for Eliza is a program that uses your computer
monitor to send out AM short wave radio signals. You
can then hear computer generated music in your radio.
it teaches you that your computer can be observed.
Tempest for Eliza works with every monitor, every
resolution. you don't have to be root.
