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...
Compact linkable ring signatures and applications

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
font style='font-size:12px;'>
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...

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

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...

font style='font-size:12px;'>
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...

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...
