Bkw algorithm dissection
WebA comprehensive analysis of the existing LPN solving algorithms, both for the general case and for the sparse secret scenario, shows that for a sparse secret there is another algorithm that outperforms BKW and its variants. The Learning Parity with Noise problem (LPN) is appealing in cryptography as it is considered to remain hard in the post … 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.
