ABE with improved auxiliary input for big data security

作者：

Highlights：

• The first CP-ABE and KP-ABE schemes in the improved auxiliary input model are proposed.

• The proposed schemes are CPA secure in the improved auxiliary input model.

• An improved strong extractor from modified Goldreich–Levin theorem is constructed.

• The proposed ABE schemes are implemented on two different platforms.
