"When I accepted the commission, I had something of an epiphany in the research I did about the agency, actually the science of espionage. I realized there is a connection between the sciences and the invisible forces of man."

"What affected me most profoundly was the realization that the sciences of cryptography and mathematics are very elegant, pure sciences. I found that the ends for which these pure sciences are used are less elegant."

"I chose to deal with the science of cryptography. Cryptography began in mathematics. Codes were developed, even from Caesar's time, based on number theory and mathematical principles. I decided to use those principles and designed a work that is encoded."
