Hello!
I read about overlooking of monitor radiation.
Introder can scan the electron-beam radiation from
electron-gun. He simple transmit this radiation to self
electron-gun and sinchronize frequance. This method work
with b/w monitor. The overlooking of color-monitor more
dificult - introder will see 4 gradation of gray (all guns
off, work one, two, three guns). But we can select spesial
colors (red-blue or blue-green) and allways will work only
one (or two) guns. In this way introder will see dark (or
light) gray screen without any information!!!
Is it corect? Do now present more improve overlooking
system?
Some words about DES - I spoke with one cryptoanalisyst from
KGB and he sow, that for number crypto algotitm c(key, text)
(key is keyLength tall) present f(key, text), that for all
key1 and key2 present key with length keyLength, that
c(key2, c(key1, text))==f(key, text).
He also say, that now present f() for c()=des(), more f() wery
like des().
That`s why for decrypting of des(k1, des(k2, ... des(kN, text) ... ))
we must try 2^56 keys with spetial function.
