UC-Commitment Schemes with Phase-Adaptive Security from Trapdoor Functions
Commitment Universal Composability Global Random Oracle
2019/5/21
We propose a generic framework for perfectly hiding UC-Commitment schemes in the Global Random Oracle model of Canetti \textit{el at.} (CCS 14). The main building block of our construction is a novel ...
We define a new UC functionality (DL-extractable commitment scheme) that allows committer to open a commitment to a group element gxgx; however, the simulator will be able to extract its discrete loga...
A Post-Quantum UC-Commitment Scheme in the Global Random Oracle Model from Code-Based Assumptions
Commitment Scheme Universal Composability
2019/2/27
In this work, we propose the first post-quantum UC-commitment scheme in the Global Random Oracle Model, where only one non-programmable random oracle is available. The security of our proposal is base...
Efficient UC Commitment Extension with Homomorphism for Free (and Applications)
cryptographic protocols UC
2018/11/5
Homomorphic universally composable (UC) commitments allow for the sender to reveal the result of additions and multiplications of values contained in commitments without revealing the values themselve...
