WebOct 22, 2024 · In the cryptographic literature this is known as the Learning With Errors problem (LWE). The reason cryptography based on LWE gets called lattice-based cryptography is because the proof that LWE is hard relies on the fact that finding the shortest vector in something called a lattice is known to be NP-Hard. 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
