[PDF] Top 20 Rotational cryptanalysis of round-reduced Keccak

... All the operations on the indices shown in the pseudo-code are done modulo 5. A denotes the complete permutation state array and A[x,y] denotes a particular lane in that state. B[x,y], C[x], D[x] are 64-bit intermediate ... See full document

... The Concept of Yoyo Cryptanalysis. Yoyo attacks are closely related to boomerangs. In both techniques, the adversary first lets the oracle encrypt chosen texts, observes the corresponding encryptions and ... See full document

... The most significant cryptanalysis of reduced round Salsa and ChaCha had been described in [1]. After that there are minor tweaks over that technique, but no significant improvement in reducing the ... See full document

... There is a trade-off between the time complexity and the data complexity of the attack, as depicted in Table 1. To reduce the time complexity as much as possible, we assume to have access the full codebook. In this case, ... See full document

... In this work, we presented impossible differential attacks against reduced-round versions of all the 6 SKINNY’s variants. All of these attacks use the same impos- sible differential distinguisher that ... See full document

... Another classical attack against modern ciphers is the linear attack introduced by Matsui in [24]. We again refer to [21] for an introduction to linear cryptanalysis. Our goal here is to find linear masks ... See full document

... Abstract. The GOST hash function family has served as the new Russian national hash standard (GOST R 34.11-2012) since January 1, 2013, and it has two members, i.e., GOST- 256 and GOST-512 which correspond to two ... See full document
