(Linkable) Ring Signature from Hash-Then-One-Way Signature
ring signature linkable ring signature lattice-based cryptography
2019/5/28
In this paper, we revisit the generic construction of ring signatures from hash-then-one-way type (Type−HType−H) signatures proposed by Abe et al. (AOS) in 2004 and made the following cont...
Generic Construction of Linkable Ring Signature
ring signature linkable ring signature generic construction
2019/4/11
We propose a generic construction of linkable ring signature from any compatible ring signature scheme and one-time signature scheme. Our construction has both theoretical and practical interest. In t...
Raptor: A Practical Lattice-Based (Linkable) Ring Signature
ring signatures lattice based cryptography falcon signature
2018/11/14
We present (linkable) Raptor, the first lattice-based (linkable) ring signature that is practical. Our scheme is as fast as classical solutions; while the size of the signature is roughly 1.3 KB per u...
Post-Quantum One-Time Linkable Ring Signature and Application to Ring Confidential Transactions in Blockchain (Lattice RingCT v1.0)
Linkable Ring Signature Lattice-Based Cryptography Post-Quantum Cryptography
2018/5/2
In this paper, we construct a Lattice-based one-time Linkable Ring Signature (L2RS) scheme, which enables the public to verify if two or more signatures were generated by same signatory, whilst still ...
RingCT 2.0: A Compact Accumulator-Based (Linkable Ring Signature) Protocol for Blockchain Cryptocurrency Monero
Cryptographic Currency Anonymity
2017/9/25
In this work, we initially study the necessary properties and security requirements of Ring Confidential Transaction (RingCT) protocol deployed in the popular anonymous cryptocurrency Monero. Firstly,...
