1,702 Views
This video belongs to the following courses
Organization: Khan Academy
Speaker: Brit Cruise
In cryptography, the one-time pad (OTP) is a type of encryption which has been proven to be impossible to crack if used correctly. Each bit or character from the plaintext is encrypted by a modular addition with a bit or character from a secret random key (or pad) of the same length as the plaintext, resulting in a ciphertext.
