Improved generalized birthday attack
Witryna1 sty 2002 · We study a k -dimensional generalization of the birthday problem: given k lists of n -bit values, find some way to choose one element from each list so that the … Witrynathe rst published collision nding attacks on reduced-round versions of Keccak-384 and Keccak-512, providing actual collisions for 3-round versions, and describing an attack which is 245 times faster than birthday attacks for 4-round Keccak-384. For Keccak-256, we increase the number of rounds which can be attacked to 5. All these results …

WitrynaPerformance-wise, our protocol is more efficient than previous LPN-based schemes, such as the many variants of the Hopper-Blum (HB) protocol and the aforementioned protocol from Eurocrypt’11. Our implementation results show that it is even comparable to the standard challenge-and-response protocols based on the AES block-cipher.
