Recently, sieving has also become an important tool in code-based cryptanalysis. Specifically, a variant of the information-set decoding (ISD) framework, commonly used for attacking cryptographically relevant instances of the decoding problem, has been introduced that involves a sieving subroutine. The resulting sieving-based ISD framework yields complexities close to the best-performing classical algorithms for the decoding problem. It is therefore natural to ask how well quantum versions perform. In this work, we introduce the first quantum algorithms for code sieving by designing quantum variants of the aforementioned sieving subroutine. In particular, using quantum-walk techniques, we provide a speed-up over classical code sieving and over a variant using Grover’s algorithm. Our quantum-walk algorithm exploits the structure of the underlying search problem by adding a layer of locality sensitive filtering, inspired by a quantum-walk algorithm for lattice sieving. We complement our asymptotic analysis of the quantum algorithms with numerical results, and observe that our quantum speed-ups for code sieving behave similarly as those observed in lattice sieving. In addition, we show that a natural quantum analog of the sieving-based ISD framework does not provide any speed-up over the first quantum ISD algorithm. Our analysis highlights that the framework should be adapted in order to outperform state-of-the-art quantum ISD algorithms.</p>","PeriodicalId":11130,"journal":{"name":"Designs, Codes and Cryptography","volume":"20 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existence of symplectic spreads is known, but the construction of a special spread for every odd prime power <i>q</i> is a main result of this paper.

This generalization corresponds to the fact that a vectorial function <span>(F:mathbb {F}_2^nmapsto mathbb {F}_2^m)</span> sums to a nonzero value over every <i>k</i>-dimensional affine subspace of <span>(mathbb {F}_2^n)</span>, for some <span>(kle n)</span> (APNness corresponds to <span>(k=2)</span>).

We study in the present paper the case of vector (i.e. linear) subspaces, which is much less simple to handle. The sum depends on a coefficient in subspace polynomials.

We derive several other results and we show that the set of values <i>k</i> such that the inverse function is not <i>k</i>th-order sum-free is stable when adding two values of <i>k</i> whose product is smaller than <i>n</i> (and when subtracting two values under some conditions).
