Introduction to Cryptography: One time pads and stream ciphers

WebIn the last few lectures we've explored the one-time pad encryption scheme. And shown that it achieves our definition of perfect secrecy. And indeed, the one-time pad has been used in the real world. A famous example is the red phone that connected Washington DC and Moscow in the 1980s, where the keying material was shared by trusted couriers ... WebJan 16, 2024 · The one-time pad has the property that (as long as one key is only used for one encryption) the ciphertext contains (information theoretically) no information about the plaintext.
