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. WebbIt is commonly accepted that this paper was the starting point for development of modern cryptography. Shannon was inspired during the war to address "[t]he problems of cryptography [because] secrecy systems furnish an interesting application of communication theory". Shannon identified the two main goals of cryptography: secrecy …
