Traceable and linkable ring signatures, traceable range proofs and applications on regulatable privacy-preserving blockchains
regulatable blockchain privacy preserving decentralization
2019/8/19
Privacy protection has been extensively studied in the current blockchain research field. As representations, Monero and Zerocash have realized completely anonymous and amount-hiding transactions. How...
We describe an efficient linkable ring signature scheme, compact linkable spontaneous anonymous group (CLSAG) signatures, for use in confidential transactions. Compared to the existing signature schem...
Ring Signatures: Logarithmic-Size, No Setup --- from Standard Assumptions
ring signatures linkable ring signatures standard model
2019/3/1
Ring signatures allow for creating signatures on behalf of an ad hoc group of signers, hiding the true identity of the signer among the group. A natural goal is to construct a ring signature scheme fo...
It wasn't me! Repudiability and Unclaimability of Ring Signatures
public-key cryptography Ring signatures
2019/2/27
Ring signatures, introduced by [RST01], are a variant of digital signatures which certify that one among a particular set of parties has endorsed a message while hiding which party in the set was the ...
Post-quantum verifiable random functions from ring signatures
ring signatures quantum oracles
2019/1/2
One of the greatest challenges on exchanging seemingly random nonces or data either on a trusted or untrusted channel is the hardness of verify- ing the correctness of such output. If one of the parti...
Short Lattice-based One-out-of-Many Proofs and Applications to Ring Signatures
lattice-based cryptography zero-knowledge proof ring signature
2018/8/28
In this work, we construct a short one-out-of-many proof from (Module-SIS) lattices, allowing one to prove knowledge of a secret associated with one of the public values in a set. The proof system fol...
Towards Practical Lattice-Based One-Time Linkable Ring Signatures
lattice-based cryptography ring signature scheme anonymous cryptocurrency
2018/1/31
Ring signatures, as introduced by Rivest, Shamir, and Tauman (Asiacrypt ’01), allow to generate a signature for a message on be half of an ad-hoc set of parties. To sign a message, only the public key...
Post-Quantum Zero-Knowledge Proofs for Accumulators with Applications to Ring Signatures from Symmetric-Key Primitives
privacy-preserving cryptography provable security accumulator
2017/11/29
In this paper we address the construction of privacy-friendly cryptographic primitives for the post-quantum era and in particular accumulators with zero-knowledge membership proofs and ring signatures...
Unlinkable and Strongly Accountable Sanitizable Signatures from Verifiable Ring Signatures
Sanitizable signature Ring signature Unlinkability
2017/6/27
A Unlinkable Sanitizable Signature scheme (USS) allows a sanitizer to modify some parts of a signed message such that nobody can link the modified signature to the original one. A Verifiable Ring Sign...
Short Accountable Ring Signatures Based on DDH
Accountable ring signatures group signatures one-out-of-many zero-knowledge proofs
2015/12/29
Ring signatures and group signatures are prominent cryptographic primitives offering a combination
of privacy and authentication. They enable individual users to anonymously sign messages on behalf o...
Sub-linear Blind Ring Signatures without Random Oracles
ring signatures blind ring signatures standard model
2014/3/7
Ring signatures allow a signer to anonymously sign a message on behalf of a set of arbitrarily chosen signers called a ``ring''. Blind signatures, on the other hand, allow a user to obtain a signature...
A Framework for Efficient Signatures，Ring Signatures and Identity Based Encryption in the Standard Model
Framework Efficient Signatures Ring Signatures Identity Based Encryption Standard Model
2010/3/16
In this work, we present a generic framework for constructing e±cient signature scheme, ring
signature schemes, and identity based encryption schemes, all in the standard model (without
relying on r...
Ring signature was proposed to keep signer’s anonymity when
it signs messages on behalf of a “ring” of possible signers. In this paper,
we propose a novel notion of ring signature which is called at...
Pointcheval and Stern introduced in 1996 some forking lemmas useful to prove
the security of a family of digital signature schemes. This family includes, for
example, Schnorr's scheme and a modi cat...
