if you want to have fun with tempest, there is a nice programme at http://www.erikyyy.de/tempest/ you can actually receive music on a AM radio threw the screen of your computer. But is tempest still a real thread to computer security? And if the answer is yes, the best (cheap, effective and easy) solution would be "white noise"? is there software able to do that sort of random noise? Greeting Steven Meyer 2005/10/27, Gilbert Fernandes <gilbert.fernandes () spamcop net>:
There used to be a name for a technology (or way of implementing technology) to prevent electronic eavesdropping.It's called white noise. You need real random to produce real white noise. Another solution is to use microphones and produce inverted sound waves to "cancel" sound. It can be done. White noise is cheaper but if your random source is not really random, it can be circumvented. Think of the quality of random you need the same one as required to have a proper implementation of OTP ciphers. -- unzip ; strip ; touch ; grep ; finger ; mount ; fsck ; more ; yes ; fsck ; umount ; sleep
