Abstract :
We analyze recently proposed encryption algorithm Puzzle, aimed at efficient (real time) encryption of video streams. We show some weaknesses in the generation of components used for encryption. Moreover, we present a known plaintext attack on Puzzle. Some ideas on design of video encryption algorithms are discussed as well
