[PDF] Top 20 Cryptanalysis of Round-Reduced LED

... The main contribution of this work is actually the idea of multicollisions and their applications. The vast majority of our results/attacks, in particular the attacks that penetrate through the largest number of rounds, ... See full document

... TWEAKEY. At ASIACRYPT 2014, Jean et al. [18] proposed the TWEAKEY framework together with three software-efficient tweakable block ciphers based on the AES round function Deoxys-BC , Joltik-BC , and Kiasu-BC . ... See full document

... The linear cryptanalysis shown by the designers [6] did not consider the depen- dence of the S-box. The 126-round linear characteristic eliminated by 42-round linear approximation is not accurate, ... See full document

... In cryptanalysis, we very often study the problem of distinguishing distributions, one distribution that describes the variable of the number of certain events that occur at random and another distribution that ... See full document

... Regarding SIMON-64, the squared correlation matrix which we are able to build and process holds masks with Hamming weight ≤ 6. Using only the matrix and going for more than 20 rounds, the best squared correlation we ... See full document

... Specifically, for SIMON128, where the number denotes the block length, a 34-round linear characteristic with correlation 2 −61 is found, which is the longest linear characteristic that can be used in a key- ... See full document

... In the attack the adversary knows 640-bit hash — first 10 lanes of the state after 4 rounds. When we go back from the hash to θ in the 4th round, 10 lanes of bits are known but their places in the state have ... See full document

... Towards cryptanalysis, we are interested to input a difference at the initial state (call it Input Differential or ID) and then try to obtain certain biases corresponding to combinations of some output bits (call ... See full document

... Near-optimal Differential Trails. Boomerangs that employ a single char- acteristic are of limited expressiveness as we noticed strong differential clustering effects in Sparx. For boomerangs, they are particularly strong ... See full document

... In this paper, we have presented a preimage attack on the 2 rounds of round- reduced Keccak-384. The attack is not yet practical but it is much better than the existing best-known attack in term of the time ... See full document

... In the initial setting, all the 1600 state bits obtained after the first permutation are unknown, and we aim to recover them. Once this state is recovered, we can run the permutation backwards and recover the secret key. ... See full document

... The attacks by Wang et al. on MD5 [24] and SHA-1 [23] followed by the SHA-3 competition [4] have led to a flurry in the area of hash function cryptanalysis. Modern cryptanalytic approaches target both hash ... See full document

... The idea behind the related-key attacks on Present is to benefit from the slow mixing in the key scheduling algorithm which makes use of only one or two S- box operations (depending on the version) during each iteration. ... See full document
