On Cryptographic Anonimity and Unpredicatbility in Secret Sharing

Abstract: We revisit the notions of cryptographic anonymity and share unpredictability in secret sharing, introducing more systematic and fine grained definitions. We derive tight negative and positive results characterizing access structures with respect to the generalized definitions.
