  bibo_abstract:
  - A modular approach to constructing cryptographic protocols leads to simple designs
    but often inefficient instantiations. On the other hand, ad hoc constructions
    may yield efficient protocols at the cost of losing conceptual simplicity. We
    suggest a new design paradigm, structure-preserving cryptography, that provides
    a way to construct modular protocols with reasonable efficiency while retaining
    conceptual simplicity. A cryptographic scheme over a bilinear group is called
    structure-preserving if its public inputs and outputs consist of elements from
    the bilinear groups and their consistency can be verified by evaluating pairing-product
    equations. As structure-preserving schemes smoothly interoperate with each other,
    they are useful as building blocks in modular design of cryptographic applications.
    This paper introduces structure-preserving commitment and signature schemes over
    bilinear groups with several desirable properties. The commitment schemes include
    homomorphic, trapdoor and length-reducing commitments to group elements, and the
    structure-preserving signature schemes are the first ones that yield constant-size
    signatures on multiple group elements. A structure-preserving signature scheme
    is called automorphic if the public keys lie in the message space, which cannot
    be achieved by compressing inputs via a cryptographic hash function, as this would
    destroy the mathematical structure we are trying to preserve. Automorphic signatures
    can be used for building certification chains underlying privacy-preserving protocols.
    Among a vast number of applications of structure-preserving protocols, we present
    an efficient round-optimal blind-signature scheme and a group signature scheme
    with an efficient and concurrently secure protocol for enrolling new members.@eng
