Shortest independent vector problem
SpletShortest Vector Problem is an instance of lattice problems that are used as a basis for secure cryptographic schemes. For more than 30 years now, the Shortest Vector Problem has been at the heart of a thriving research field and finding a new efficient algorithm turned out to be out of reach. Splet01. apr. 2024 · To that end, a few recent results have shown quantitative hardness for the Closest Vector Problem (CVP p) [2], [28], and the Shortest Vector Problem (SVP p) [24] which are closely related. In particular, assuming SETH, [2] , [28] showed that there is no 2 ( 1 − ε ) n -time algorithm for CVP p or SVP ∞ for any ε > 0 and for 1 ≤ p ≤ ∞ ...
