... PRIDE is a SPN structure block cipher with 64-bit block cipher and 128-bit key. The round function consists of three operations: The state is XORed with the round key, fed into 16 paralled 4-bit Sboxes and then ... See full document

... A natural scenario to adapt this tweaked framework without truncation is to generate short preimages for certain hash primitives by fixing partial values of the padding. The idea of generating short preimages by fixing ... See full document

... We exemplify the numbers for the attack on the first example in the table where we have a 128-bit state, one S-box per layer, 16 allowed chosen plaintext/ciphertext pairs and a 256-bit key. In the best attack, we ... See full document

... Abstract. Zorro is an AES-like lightweight block cipher proposed in CHES 2013, which only uses 4 S-boxes per round. The designers showed the resistance of the cipher against various attacks and concluded the cipher has a ... See full document
