Webb31 aug. 2010 · Shannon defined ideal secrecy that requires the unicity distance is unlimited, that is to say, no matter how much material is intercepted, the enemy still does not obtain a unique solution to the cipher but is left with many alternatives. It is possible in any language to approximate such behavior. Webb22 aug. 2013 · Shannon's Theorem • The signal-to-noise ratio (S/N) is usually expressed in decibels (dB) given by the formula: • 10 * log10 (S/N) • so for example a signal-to-noise ratio of 1000 is commonly expressed as • 10 * log10 (1000) = 30 dB. Shannon's Theorem • Here is a graph showing the relationship between C/B and S/N (in dB):
