... Designing an encryption system to support a DFA-type functionality provides a new set of challenges. It is useful to compare them to those in building a boolean formula (ABE) type system. In existing ABE systems a ... See full document

... Remark: At first glance, there seems to be a circularity issue in trying to prove IND-CCA security of our scheme. That is, in order to prove indistinguishability of the main hybrids, we require to first erase α which ... See full document
