Hi list,
Interesting. Great work! I had been looking *generic* predicate
encryption for some time. Encryption over specific predicates

A group member asked me to elaborate on:
- No knowledge of which groups can be successfully authenticated is
known to the verifier
What this tries to say is that the verifier doesn't need to have a list of
all authenticable groups nor can the verifier draw any conclusions about

This is fairly interesting: AFAIK the first generalization of
predicate encryption to support disjunctions. I find the result mostly
interesting mathematically, since I expect we won't be seeing
predicate encryption in widespread use anytime soon due to complexity
and regulatory concerns.
