WebWe provide the first time-memory trade-offs for the BKW algorithm. For instance, we show how to solve LPN in dimension k in time and memory . Using the Dissection technique due to Dinur et al. (Crypto ’12) and a novel, slight generalization thereof, we obtain fine-grained trade-offs for any available (subexponential) memory while the running ...
WebMay 1, 2024 · The k-xor or Generalized Birthday Problem aims at finding, given k lists of bit-strings, a k-tuple among them XORing to 0.If the lists are unbounded, the best classical (exponential) time complexity has withstood since Wagner’s CRYPTO 2002 paper. If the lists are bounded (of the same size) and such that there is a single solution, the … WebAug 9, 2024 · The BKW algorithm consists of two parts, reduction and hypothesis testing. 3.1 Reduction We divide samples into categories based on b position values in the a vectors. Two samples should be in the same category if and only if the b position values get canceled when adding or subtracting the a vectors.
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 WebThis paper presents new improvements for BKW-style algorithms for solving LWE instances and introduces a new reduction step where the last position is partially reduced in an iteration and the reduction is finished in the next iteration, allowing non-integer step sizes. 5 PDF LPN Decoded Andre Esser, Robert Kübler, Alexander May Computer Science
