| Abstract(in English) | Meet-in-the-middle (MITM) attack is a powerful cryptanalytic method for block ciphers. Several attacks for block ciphers are applied to stream ciphers, but the MITM attack has not been applied to stream ciphers yet. In this paper, we propose a first MITM attack for stream cipher. In addition, the attack is applied to a stream cipher Grain v1 which is one of eSTREAM portfolio. Finally, we show the efficiency of our MITM attack. |
