Webproblems in cryptography. This work surveys most of the major developments in lattice cryptography over the past ten years. The main focus is on the foundational short integer solution (SIS) and learning with errors (LWE) problems (and their more efficient ring-based variants), their provable hardness assuming the worst-case intractability of WebSearch-LWEandDecision-LWE.WenowstatetheLWEhardproblems. Thesearch-LWEproblem is to find the secret vector sgiven (A,b) from A s,χ. The decision-LWE problem is to distinguish A s,χ from the uniform distribution {(A,b) ∈ Zm×n q× Z n: A and b are chosen uniformly at random)}. [55] provided a reduction from search-LWE to decision-LWE . WebApr 6, 2024 · Download PDF Abstract: We show direct and conceptually simple reductions between the classical learning with errors (LWE) problem and its continuous analog, CLWE (Bruna, Regev, Song and Tang, STOC 2024). This allows us to bring to bear the powerful machinery of LWE-based cryptography to the applications of CLWE. For example, we … birthday cake delivery maryland
