Improved Meet-in-the-Middle Attacks on ARIA

摘要：

In this paper we apply meet-in-the-middle attacks to reduced-round ARIA. We find some novel distinguishes of ARIA, and propose improved attacks against ARIA up to 8 rounds based on them. We lower the complexities of 8/7/6-round attacks, and balance the data, time, and precomputation complexities of 5-round attack. Our result is the best one of all kinds of cryptanalysis on ARIA known so far.
