text: 'Blind signatures allow users to obtain signatures on messages hidden from
the signer; moreover, the signer cannot link the resulting message/signature pair
to the signing session. This paper presents blind signature schemes, in which
the number of interactions between the user and the signer is minimal and whose
blind signatures are short. Our schemes are defined over bilinear groups and are
proved secure in the common-reference-string model without random oracles and
under standard assumptions: CDH and the decision-linear assumption. (We also give
variants over asymmetric groups based on similar assumptions.) The blind signatures
are Waters signatures, which consist of 2 group elements. Moreover, we instantiate
partially blind signatures, where the message consists of a part hidden from the
signer and a commonly known public part, and schemes achieving perfect blindness.
We propose new variants of blind signatures, such as signer-friendly partially
blind signatures, where the public part can be chosen by the signer without prior
agreement, 3-party blind signatures, as well as blind signatures on multiple aggregated
messages provided by independent sources. We also extend Waters signatures to
non-binary alphabets by proving a new result on the underlying hash function. '
