Witryna8 maj 2016 · The best published algorithm for solving it at Asiacrypt 2014 improved the classical BKW algorithm by using covering codes, which claimed to marginally compromise the 80-bit security of HB variants, LPN-C and Lapin. 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. can people survive bowel cancer
