Cryptographic primitives in blockchains

Journal of Network and Computer Applications, 2019
Abstract Blockchain, as one of the crypto-intensive creatures, has become a very hot topic recently. Although many surveys have recently been dedicated to the security and privacy issues of blockchains, there still lacks a systematic examination on the cryptographic primitives in blockchains.

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 ...
