.... KM00] and Rijndael s highly structured round function allowed relatively straightforward extensions of attacks that were already known [FKS 00a, Luc00, GM00] Since the AES candidates were published in 1998, several new cryptanalytic attacks were published: impossible di#erential cryptanalysis [BBS99a, BBS99b], mod n cryptanalysis [KSW99] boomerang attacks [Wag99, KKS00a] and slide attacks [BW99, BW00] Twofish s resistance to these hitherto unknown attacks speaks of its security. 2.3 Power Analysis and Block Ciphers At the Second AES Candidate Conference, some people looked at the AES submissions ....

For IDEA, the most striking improvement is in the number of rounds that can be broken faster than brute force as a function of year (see Table 2) The three attacks are very di#erent, and are not simply improvements of each other. 3.2 Current Status IDEA is still a highly regarded cipher. ....

....description and the analysis. 2.2 The Rectangle Attack Converting adaptive chosen plaintext and ciphertext distinguishers into key recovery attacks pose several difficulties. Unlike the regular known plaintext, chosen plaintext, or chosen ciphertext distinguishers, using the regular methods of [3, 17, 12, 4, 5, 16] to use adaptive chosen plaintext and ciphertext distinguishers in key recovery attacks fail, as these techniques require the ability to directly control either the input or the output of the encryption function. In [11] the amplified boomerang attack is presented. This is a method for ....

....section to the boomerang attack. We generalized the results of [21,9] Like the rectangle attack, we have found that whenever the boomerang distinguisher succeeds then the key recovery attack also succeeds. There are various standard techniques to use distinguishers for a key recovery attack [3, 17, 12, 4, 5, 16]. The basic idea is to try all subkeys which affect the s As stated earlier, in [7] it was mistakenly claimed that t = 64. We use the correct value of 76, and derive the correct time complexity. difference (or the approximation) before and after the distinguishers (i.e. in Eb and E ) and to ....

....the distinguisher used in the attack as a combination of two much simpler parts; in this case a combination of a differential characteristic and a linear approximation. Such combinations were later used in other kinds of cryptanalysis, e.g. crypt analysis using impossible differentials [4, 3] (miss in the middle) and boomerang attacks [15] both use combinations of differential characteristics. In this paper we present an extension of differential linear cryptanalysis in which the linear probability induced by the differential characteristic is smaller than 1. We use this extension ....
