[PDF] Top 20 Cryptanalysis of Full Sprout

... In [3] the authors aim at reducing the size of the internal state used in stream ciphers while resisting to time-data-memory trade-off (TMDTO) attacks. They propose to this purpose a new design principle for stream ... See full document

... In general, one may expect that the special internal states to be stored are deduced by exhaustively searching them. However, we can deduce these states without a search-and-eliminate mechanism, reducing the time ... See full document

... Abstract. Frit is a cryptographic 384-bit permutation recently proposed by Simon et al. and follows a novel design approach for built-in countermeasures against fault attacks. We analyze the cryptanalytic security of ... See full document

... In this section, we present a biclique attack on the full TWINE-80. Firstly, we divide the key space into 2 72 subspaces of 2 8 keys each. Then for each key subspace we construct a biclique on the first 8 rounds ... See full document

... While at the hash function level, the best collision [19] and preimage [28] attacks only reach 5.5 and 6 rounds out of 10 rounds, and a 7-round limited-birthday distinguisher on Whirlpoo[r] ... See full document

... To the best of our knowledge, this is the first attack on full MORUS in the nonce-respecting setting. We note that rekeying does not prevent the attack: the biases are independent of the secret encryption key and ... See full document

... Abstract. A fast correlation attack (FCA) is a well-known cryptanalysis technique for LFSR- based stream ciphers. The correlation between the initial state of an LFSR and corresponding key stream is exploited, and ... See full document
