Structure-preserving signature schemes can be very useful in the construction of new cryptographic
operations like blind signatures. Recently several of these schemes have been proposed.
The securit...
Type 2 Structure-Preserving Signature Schemes Revisited
cryptographic schemes concrete perspective
2016/1/7
At CRYPTO 2014, Abe et al. presented generic-signer structure-preserving
signature schemes using Type 2 pairings. According to the authors, the proposed constructions
are optimal with only two group...
Structure-Preserving Signatures on Equivalence Classes and their Application to Anonymous Credentials
Public key cryptography structure-preserving signatures attribute-based anonymous credentials
2016/1/7
Structure-preserving signatures are a quite recent but important building block for many
cryptographic protocols. In this paper, we introduce a new type of structure-preserving signatures, which
all...

2016/1/5
At ASIACRYPT’14 Hanser and Slamanig proposed a new primitive called structure-preserving signatures
on equivalence classes (SPS-EQ) and used it to construct very efficient attribute-based anonymous

Strongly-Optimal Structure Preserving Signatures from Type II Pairings: Synthesis and Lower Bounds
Structure-Preserving Signatures Generic Group Model Bilinear Groups
2016/1/5
Recent work on structure-preserving signatures studies optimality of these schemes in terms of the
number of group elements needed in the verification key and the signature, and the number of pairing...
Structure-Preserving Signatures from Standard Assumptions, Revisited
public-key cryptography Standard Assumptions
2015/12/29
Structure-preserving signatures (SPS) are pairing-based signatures where all the messages, signatures
and public keys are group elements, with numerous applications in public-key cryptography. We pre...
Short Group Signatures via Structure-Preserving Signatures: Standard Model Security from Simple Assumptions
Group signatures standard model simple assumptions
2015/12/24
Group signatures are a central cryptographic primitive which allows users to sign messages
while hiding their identity within a crowd of group members. In the standard model (without the random
orac...
Efficient Fully Structure-Preserving Signatures for Large Messages

2015/12/23
We construct both randomizable and strongly existentially
unforgeable structure-preserving signatures for messages consisting of
many group elements. To sign a message consisting of N = mn group ele...

We construct a new structure-preserving signature scheme
in the efficient Type-III asymmetric bilinear group setting with signatures
shorter than all existing schemes. Our signatures consist of 3 gr...
Linearly Homomorphic Structure-Preserving Signatures and Their Applications
Structure-preserving cryptography signatures
2014/3/12
Structure-preserving signatures (SPS) are signature schemes where messages, signatures and public keys all consist of elements of a group over which a bilinear map is efficiently computable. This prop...

We present a generic transformation that allows us to use a large class of pairing-based signatures to construct schemes for signing group elements in a structure preserving way.
