Digressing for a while, Charles Babbage (born 1791) is famously credited wi= th breaking the equally famous =93Vigenere Cipher=94 that had lain unbroken= for two centuries prior to that. His modus operandi was based on his noti= cing that languages have a frequency pattern.=20 In cryptography, if the ciphertext is the same data type as the plaintext i= t is obfuscating, the illegal cryptanalyst can establish the frequency of t= he ciphertext and then use this to statistical map the ciphertext in an exp= loratory way to the plaintext that it originated from. (This statement is h= ugely over simplistic here)=20 That was the ploy that Babbage invented. The Brits are usually fairly honest people about such matters and give cred= it where credit is due. The Russian, Friedrich Wilhelm Kasiski had beaten= Charles Babbage to this invention however by ten years and it is conceded= therefore today that it is a joint invention by both Kasiski and Babbage a= t different times. Sorting and checking for repeats is an important process in cryptography to= day and a sort program such as I am using is deserving of its place in the= history of crypto technology in my view. I shall continue therefore to claim my invention of Parallel Sort (Like Bab= bage) is an independent piece of intellectual property. But who did invent =93Count Sort=94 on the other hand is something I would = like to know =96 an individual ?. Thanks again for all your helpful comments. Austin O=92Byrne.
