However, they should not be confused as the same film, they are two different films starring the same
Rip van Winkle cipher it with the random numbers he remembers were transmitted T ago, to recover the original plaintext message. The delay T represents the "key" and must be securely communicated only once. Ueli Maurer says the original Rip van Winkle cipher is completely impractical, but it motivated a new approach to provable security. J.L. Massey and I. Ingemarsson.
