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 WebWe provide several applications of these algorithms, improving the best known quantum algorithms for subset sums, the BKW algorithm, multiple-ecryption and the approximate k-list problem. Outline. In Section 2, we recall some preliminaries of quantum computing, state the di erent problems that we will solve and recall previous results. Section 3 sonia rolland miss france 2020
