Universally Composable DKG with Linear Number of Exponentiations sharing scheme to construct such a protocol. Our result holds for static adversaries corrupting a minority of the parties under the Decision Diffie-Hellman assumption in a weak common random string model in which the simulator . the common random string..Our protocol is optimistic.

On the Security Notions for Public-Key Encryption Schemesich an adversary can ask at most . (. resp.) queries before (after resp.) receiving the challenge. Excepted the trivial implications, all the other relations are strict gaps, with no polynomial reduction (under the assumption that .-. secure encryption schemes exist.) Similarly, we define different levels for non-malleability (denoted (.,.)-..)

Universally Composable DKG with Linear Number of Exponentiationsehave honestly, each party computes .(3.5.) exponentiations, and otherwise each party computes .(..) exponentiations, where . is the number of parties. In previous constructions each party always computes Ω(..) exponentiations.

Group Signatures with Separate and Distributed Authoritiesralization, these two authorities are respectively distributed among multiple entities in a manner efficient enough for practical applications. Previous group signature schemes have only offered one or the other of these two properties. Further, we formalize the security properties.
