Hardness of Learning Problems over Burnside Groups of Exponent 3
Nelly Fazio and Kevin Iga and Antonio Nicolosi and Ludovic Perret and William E. Skeith III
Abstract: In this work we investigate the hardness of a computational problem introduced in the recent work of Baumslag et al. In particular, we study the $B_n$-LHN problem, which is a generalized version of the learning with errors (LWE) problem, instantiated with a particular family of non-abelian groups (free Burnside groups of exponent 3). In our main result, we demonstrate a random self-reducibility property for $B_n$-LHN. Along the way, we also prove a sequence of lemmas regarding homomorphisms of free Burnside groups of exponent 3 that may be of independent interest.
