It is inspired by Brent Waters' scheme which is a large universe attribute-based encryption using bilinear map. It is a very practical scheme but this scheme may not be security with the developing quantum computer. So we extend their good idea of large universe attribute-based encryption to lattices based cryptosystem. And our scheme is the first large universe ABE scheme from lattices. In a large universe ABE system any string can be used as attribute and attributes need not be determined at system setup.
