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.

Witryna1 lis 2024 · In this study, the authors present some new algorithms for the unbalanced generalised birthday problem (UGBP), which was proposed by Nikolić and Sasaki in their attacks on the generalised birthday problem (GBP). The authors’ first idea is simple, which uses some precomputing to convert UGBP into GBP. Witryna27 maj 2024 · The combined structure requires us to considering both stream and block cipher attacks. 1.

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. Witrynafor generalized birthday attacks Daniel J.
