comment What is Attribute Based Encryption?
informally, intuitively, i believe a technique achieved by PKE could also be achieved by SKE. ABE may be lot cleanly achieved in PKE but should be possible in SKE too, imagine a master secret key split into key shares per attribute or something but i did not think through how ABE can be realized using SKE
