Evidence Performed by Claude Shannon

  • Name
    Bell Laboratories Wartime Cryptography Research
  • Description

    During World War II, the United States required absolutely secure communication systems to protect military secrets from sophisticated enemy interception and decryption efforts. Claude Shannon worked on top-secret fire-control systems and cryptographic projects at Bell Labs, culminating in his seminal report titled "A Mathematical Theory of Cryptography." His research mathematically proved that the "one-time pad" cipher is completely unbreakable, establishing the absolute limits of secure communications and directly assisting the Allied war effort.
