Improved Related-Key Impossible Differential Attacks on Reduced-Round AES-192

چکیده
In this paper, we present several new related-key impossible differential attacks on 7and 8-round AES-192, following the work of Eli Biham and Orr Dunkelman et al. [1]. We choose another relation of the two related keys, start attacks from the very beginning(instead of the third round in [1]) so as to improve the data and time complexities of their attacks. Furthermore, we point out and correct an error in [1] when they attacked 8-round AES-192, then present our attacks. Finally, we give a new related-key differential attack on 7-round AES-192, which mainly uses a property of MixColumns operation of AES.

Related-Key Impossible Differential Attacks on 8-Round AES-192
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 observations to substantially improve the data and time complexities of their attacks. Amongst our results, we present a related-key attack on 7-round AES-192 with data complexity of 2 chosen plaintexts (instead of 2). O...
متن کاملNew Impossible Differential Attacks on AES
In this paper we apply impossible differential attacks to reduced round AES. Using various techniques, including the early abort approach and key schedule considerations, we significantly improve previously known attacks due to Bahrak-Aref and Phan. The improvement of these attacks leads to the best known impossible differential attacks on 7-round AES-128 and AES-192, as well as to the best kno...
متن کاملRelated-Key Impossible Differential Attacks on Reduced-Round AES-256
In this paper we examine the strength of AES-256 against the related-key impossible differential attack, following the work in [1] and [2]. Firstly, we present a carefully chosen relation between the related keys, which can be extended to 8-round(even more rounds) subkey differences. Then, we construct a 5.5-round related-key impossible differential. Using the differential, we present an attack...
متن کاملImpossible Differential Cryptanalysis on Deoxys-BC-256
Deoxys is a final-round candidate of the CAESAR competition. Deoxys is built upon an internal tweakable block cipher Deoxys-BC, where in addition to the plaintext and key, it takes an extra non-secret input called a tweak. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block cipher. First, we find a 4.5-round...
متن کاملThe (related-key) impossible boomerang attack and its application to the AES block cipher
The Advanced Encryption Standard (AES) is a 128-bit block cipher with a user key of 128, 192 or 256 bits, released by NIST in 2001 as the next-generation data encryption standard for use in the USA. It was adopted as an ISO international standard in 2005. Impossible differential cryptanalysis and the boomerang attack are powerful variants of differential cryptanalysis for analysing the security...
