WebJan 25, 2024 · 3.5 Dissection c-sum \(^+\) BKW Algorithm. Esser et al. borrowed the dissection technique from [14, 37] to optimize the running time of their c-sum algorithm, referred to as dissection c-sum. The dissection c-sum perfectly fits into our \(c\text {-sum}^+\) problem even better with only minor adaptions. Webin improved algorithms for hard instances of the knapsack problem [2,13]. The K-tree algorithm is also closely related to the BKW algorithm for the learning parity with noise (LPN) problem [7], and the BKW extension to the learning with errors (LWE) problem [1]. We consider the most relevant GBP variant in cryptanalysis. For integer
