Implementation and Optimization of Zero-Knowledge Proof Circuit Based on Hash Function SM3

Sensors, 2022
With the increasing demand for privacy protection in the blockchain, the universal zero-knowledge proof protocol has been developed and widely used. Because hash function is an important cryptographic primitive in a blockchain, the zero-knowledge proof ...

Quantum advantage for probabilistic one-time programs

Nature Communications, 2018
Information Theoretically-secure deterministic programs that self-destruct after a single use are known to be impossible to implement. Here, the authors use quantum states to implement a probabilistic version of this fundamental cryptographic primitive ...
