Quantum protocols for Rabin oblivious transfer
Erika Andersson, Akshay Bansal, James T. Peat +2
Rabin oblivious transfer is the cryptographic task where Alice wishes to receive a bit from Bob but it may get lost with probability 1/2. In this work, we provide protocol designs…
Experimental asymmetric relativistic zero-knowledge proofs with unconditional security
Chen-Xun Weng, Ming-Yang Li, Nai-Rui Xu +6
Zero-knowledge proofs (ZKPs) are widely applied in digital economies, such as cryptocurrencies and smart contracts, for establishing trust and privacy between untrusted parties. Cl…
String commitment from unstructured noise
Jiawei Wu, Masahito Hayashi, Marco Tomamichel
Noisy channels are a foundational resource for constructing cryptographic primitives such as string commitment and oblivious transfer. The noisy channel model has been extended to…
On the composable security of weak coin flipping
Jiawei Wu, Yanglin Hu, Akshay Bansal +1
Weak coin flipping is a cryptographic primitive in which two mutually distrustful parties generate a shared random bit to agree on a winner via remote communication. While a stand-…
Quantum secure direct communication with private dense coding using general preshared quantum state
Jiawei Wu, Gui-Lu Long, Masahito Hayashi
We study quantum secure direct communication by using a general preshared quantum state and a generalization of dense coding. In this scenario, Alice is allowed to apply a unitary…
