New Impossible Differential Attacks on AES
نویسندگان
چکیده
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 known impossible differential attacks on 8-round AES256.

New Impossible Differential Attacks on AES
Some new near 5 rounds impossible differential properties of AES are first presented in this paper, in which active bytes of 1 round or 5 round are in different columns and in favor of extension. Additionally, we first propose the complexities expressions of an universal impossible differential attack, which can help us to rapidly search appropriate impossible differential paths. More important...
متن کاملImproved Related-Key Impossible Differential Attacks on Reduced-Round AES-192
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...
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 کاملA new method for accelerating impossible differential cryptanalysis and its application on LBlock
Impossible differential cryptanalysis, the extension of differential cryptanalysis, is one of the most efficient attacks against block ciphers. This cryptanalysis method has been applied to most of the block ciphers and has shown significant results. Using structures, key schedule considerations, early abort, and pre-computation are some common methods to reduce complexities of this attack. In ...
متن کاملAnalysis of Venkaiah et al.'s AES Design
This paper describes impossible differential (ID) attacks on an AES variant designed by Venkaiah et al.. They claim that their cipher has improved resistance to ID attacks due to a new MixColumns matrix with a branch number 4, which is smaller than that of the original AES. We argue against this statement. The contributions of this paper include ID distinguishers for Venkaiah et al.’s cipher, a...
