Attribute-Based Functional Encryption on Lattices

By Xavier Boyen.

In Theory of Cryptography Conference (TCC 2013), volume 7785 of Lecture Notes in Computer Science, pages 122-142. Springer, 2013.


We introduce a broad lattice manipulation technique for expressive cryptography, and use it to realize functional encryption for access structures from post-quantum hardness assumptions. Specifically, we build an efficient key-policy attribute-based encryption scheme, and prove its security in the selective sense from learning-with-errors intractability in the standard model.
