Abstract. AES is the most widely used block cipher today, and its security is one of the most important issues in cryptanalysis. After 13 years of analysis, related-key attacks wer...
This paper examines the security of AES-192 and AES-256 against a related-key rectangle attack. We find the following new attacks: 8-round reduced AES-192 with 2 related keys, 10-...
We present a 5-round distinguisher for AES. We exploit this distinguisher to develop a meet-in-the-middle attack on 7 rounds of AES192 and 8 rounds of AES-256. We also give a time-...
In this paper we examine the strength of AES against the related-key impossible differential attack, following the work of Jakimoski and Desmedt [12]. We use several additional obs...
Since Rijndael was chosen as the Advanced Encryption Standard, improving upon 7-round attacks on the 128-bit key variant or upon 8-round attacks on the 192/256-bit key variants has...
