WebWe note that in most previous works the hardness of LWE is treated only asymptotically. Indeed, it is not uncommon to hide logarithmic and constant factors in the exponent of complexity expres-sions. For example, Arora and Ge [AG11] specify the complexity of their algorithm as 2O~(n2˘), for some ˘such that q= n˘.
