"He could plainly see that the document described a technique called the one-time pad fully 35 years before its supposed invention during World War I by Gilbert Vernam, an AT&T engineer, and Joseph Mauborgne, later chief of the Army Signal Corps.Although not widely used today because it is relatively difficult to work with, the one-time pad is still viewed as one of strongest ways to encrypt a communication. The technique is distinguished by the use of a random key, shared by both parties, to encode the message and decode it; the key must be used only once and then securely disposed of."
