Abstract: Motivated by the lattice basis delegation technique due to [8], we propose an adaptively secure identity-based broadcast encryption(IBBE) scheme based on the hard worst-case lattice problems. Our construction can be generalized to obtain a hierarchical IBBE (HIBBE) scheme easily. To the best of the authors' knowledge, our construction and its variants constitute the first adaptively secure IBBE schemes from lattices, which are believed secure in the post-quantum environment.
