Simple Genius (Sean King & Michelle Maxwell 3) - Page 25
“But you’re not working for the government?”
“Does this look like a government facility to you,” he said sharply.
“Maybe.” Sean glanced over at the martial arts uniform on the door. “Karate? Kung fu?”
“Tae Kwon Do. My father made me start taking it when I entered high school.”
“So he was into martial arts?”
“No, he made me take it so I could defend myself at school. It may shock you to learn that I was something of a nerd, Mr. King. And if it’s one thing teenage boys hate, particularly teenage boys whose neck size is larger than their IQ, it’s a nerd.” Champ glanced at his watch and then picked up some papers on his desk.
Noting this Sean said quickly, “I’ll need to go over the details of the case. If you don’t want to regurgitate them again, I can always speak with Len Rivest.”
At that moment a short, stocky, gray-haired woman came in carrying a coffee tray. She handed out the cups, sugar and spoons.
Champ said, “Doris, would you ask Len Rivest to join us?”
After she left Sean turned back to Champ. “So while we’re waiting, without revealing anything confidential, what exactly is Babbage Town? The driver didn’t really know how to explain it.”
Champ didn’t look inclined to answer.
“Just background, Champ, that’s all.”
“Have you ever heard of Charles Babbage?”
“No.”
“He was instrumental in developing the blueprint for the modern computer; no small feat when you consider the man was born in 1791. He also invented the speedometer. As a lover of statistics he drew up a set of mortality tables, a standard tool in the insurance industry today. And whenever you send a letter you use the single postal rate that Babbage conceived. But in my mind the most amazing thing that Charles Babbage did was break the Vigenère polyalphabetic cipher, which had withstood all decryption attempts for nearly three centuries.”
“Vigenère polyalphabetic cipher?”
Champ nodded. “Blaise de Vigenère was a French diplomat who fashioned the cipher in the sixteenth century. It was known as a polyalphabetic because it used multiple alphabets instead of simply one. However, it lay unused for nearly two hundred years because people thought it was too complex, to hell with it being impregnable to frequency analysis. Do you
know about frequency analysis?”
“Sounds familiar,” Sean said slowly.
“It was the holy grail of the early code-breaking community. Muslims invented it in the ninth century. Now frequency analysis means what it says. You analyze how often certain letters appear in writing. In English the letter e is the most common by far, followed by the letter t and then a. That’s immensely helpful in decoding ciphers, or at least it was. Today decryption is based on the length of secret number keys and the power and speed of computers to factor those keys. All the linguistic romance has been ripped right out of it.
“A thousand years ago the substitution cipher was thought unbreakable. Yet the Muslims managed to blow it right out of the water and gave the cryptanalysts the upper hand over the encryption people for centuries. That’s why the Vigenère cipher was so revolutionary, frequency analysis was useless against it.”
Sean squirmed a bit in his seat in the face of this lengthy history lesson.
“Forgive me, Mr. King, but I promise I’ll have a point at the end.”
“No, it’s very interesting,” Sean said, stifling a yawn.
“Now, as I said frequency analysis was useless against the Vigenère monster, so craftily and uniquely was it designed. And yet old Charlie Babbage managed to put a knife right through its numeric heart.”
“How?” Sean asked.
“He attacked it from a direction that was absolutely original and indeed set the standard for cryptanalysts for generations to come. And yet he received no recognition for it because he never bothered to publish his research.”
“So how did Babbage’s discovery become known?”
“When scholars went over his notes in the twentieth century, long after the man was dead, they determined that he had been the first to do it. And at long last, here is my point. I christened this place Babbage Town as a homage to a man with a great brain but little ability in self-promotion. However, if we achieve our goals here, have no doubt that we will scream it to the heavens.” Champ smiled. “After we secure all necessary patents ensuring that we will be fabulously rich once commercial exploitations of our various inventions commence.”
“So you get a piece of the pie?”
