New Block Cipher: ARIA
نویسندگان
چکیده
In this paper, we propose a 128-bit block cipher ARIA which is an involution substitution and permutation encryption network(SPN). We use the same S-boxes as Rijndael to eliminate defects which are caused by a totally involution structure. In the diffusion layer of ARIA, a 16×16 binary matrix of the maximum branch number 8 is used to avoid some attacks well applied to the reduced round of Rijndael. ARIA uses only basic operations, S-box substitutions and XOR’s together with an involution structure so that it can be efficiently implemented on various platforms.

Internet - Draft ARIA Algorithm for SRTP
This document describes the use of the ARIA block cipher algorithm within the Secure Real-time Transport Protocol (SRTP) for providing confidentiality for the Real-time Transport Protocol (RTP) traffic and for the control traffic for RTP, the Real-time Transport Control Protocol (RTCP). It details three modes of operation (CTR, CCM, GCM) and a SRTP Key Derivation Function for ARIA.
متن کاملZero-Correlation Linear Cryptanalysis of Reduced Round ARIA with Partial-sum and FFT
Block cipher ARIA was first proposed by some South Korean experts in 2003, and later, it was established as a Korean Standard block cipher algorithm by Korean Agency for Technology and Standards. In this paper, we focus on the security evaluation of ARIA block cipher against the recent zero-correlation linear cryptanalysis. In addition, Partial-sum technique and FFT (Fast Fourier Transform) tec...
متن کاملAttacking Reduced Rounds of the ARIA Block Cipher
ARIA [4] 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 atta...
متن کاملA Meet-in-the-Middle Attack on ARIA
In this paper, we study the meet-in-the-middle attack against block cipher ARIA. We find some new 3-round and 4-round distinguishing properties of ARIA. Based on the 3-round distinguishing property, we can apply the meet-in-the-middle attack with up to 6 rounds for all versions of ARIA. Based on the 4-round distinguishing property, we can mount a successful attack on 8-round ARIA-256. Furthermo...
