ARIA [5] 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. It is claimed to offer a higher security level than AES. In this paper we present three new attacks of reduced round ARIA which shows some weaknesses of the cipher. Moreover, our attacks have the lowest memory complexity compared to existing attacks on ARIA.
