Presentation:

The One Time Pad: Breaking the Unbreakable Cipher

Speaker(s):
Date & time (UTC/GMT):
January 9, 2021 5:00 PM
Description:

The invention of the one-time pad was incorrectly attributed to the wrong inventor for almost 100 years, until the original inventor was discovered in 2011. This follows a long tradition in cryptology of giving credit to the wrong inventor. Although the one-time pad is famous for being unbreakable, three historic examples will show three different ways in which this unbreakable cipher device was broken, with devastating results.
