Improved generalized birthday attack
WitrynaThe improved attack also allows a linear tradeoff between time and success probability, and an ith-power tradeoff between machine size and success probability. This paper … Witryna10 mar 2016 · Firstly, we give a boomerang attack on 48-step SHA-512 with a practical complexity of 2 51. The correctness of this attack is verified by providing a Type III boomerang quartet. Then, we extend the existing differential characteristics of the three hash functions to more rounds.

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.

We first study the … WitrynaThis paper presents a generalized- birthday attack that uses a machine of size 22 B/(2i+1)for time 2 to find (m 1,...,m k) such that f 1(m 1) + ··· + f k(m k) mod 2 B= 0. The exponents 2/(2i + 1) and 1/(2i + 1) are smaller than the exponents for Wagner’s original generalized-birthday attack.
