Attacking Reduced Rounds of the ARIA Block Cipher

Ewan Fleischmann, Michael Gorski, and Stefan Lucks

Abstract

ARIA is a block cipher proposed at ICISC'03. Its design is very similar to the advanced encryption standard (AES). The authors propose that on 32-bit processors, the encryption speed is at least 70% of that of the AES. They claim to offer a higher security level than AES. In this paper we present two attacks of reduced round ARIA which shows some weaknesses of the cipher. Moreover, our attacks have the lowest memory requirements compared to existing attacks on ARIA with an increase in the time complexity.
