Web(BKW) algorithm [9] for LWE with discrete Gaussian noise. The BKW algorithm is known to have (time and space) complexity 2O(n) when applied to LWE instances with a prime modulus polynomial in n[29]; in this paper we provide both the leading constant of the exponent in 2O(n) and concrete costs of BKW when applied to Search- and Decision-LWE. WebJun 5, 2024 · The slightly subexponential algorithm of Blum, Kalai and Wasserman (BKW) provides a basis for assessing LPN/LWE security. However, its huge memory …
