Public-key encryption and authentication of quantum information

M Liang, L Yang - Science China Physics, Mechanics and Astronomy, 2012 - Springer
Public-key cryptosystems for quantum messages are considered from two aspects: public-
key encryption and public-key authentication. Firstly, we propose a general construction of …

Bit-oriented quantum public-key encryption based on quantum perfect encryption

C Wu, L Yang - Quantum Information Processing, 2016 - Springer
A bit-oriented quantum public-key encryption scheme is presented. We use Boolean
functions as private-key and randomly changed pairs of quantum state and classical string …

Cryptanalysis on quantum digital signature based on asymmetric quantum cryptography

WM Shi, YM Wang, YH Zhou, YG Yang - Optik, 2018 - Elsevier
In this paper, we first study the cryptanalysis of quantum signature scheme based
asymmetric quantum cryptography. Then the results of analysis show that quantum …

Block encryption of quantum messages

M Liang, L Yang - Quantum Information Processing, 2020 - Springer
Block encryption is a fundamental cryptographic primitive in modern cryptography. However,
it is impossible for block encryption to achieve the same security as one-time pad. Quantum …

Quantum-message-oriented public-key encryption scheme beyond computational hypothesis

M Liang, L Yang - Quantum Optics II, 2012 - spiedigitallibrary.org
We propose two definitions of quantum one-way transformation and quantum trapdoor one-
way transformation beyond computational hypothesis, and give four examples. Then, we …

A quantum-classical scheme towards quantum functional encryption

A Ahuja - arxiv preprint arxiv:1703.00207, 2017 - arxiv.org
Quantum encryption is a well studied problem for both classical and quantum information.
However, little is known about quantum encryption schemes which enable the user, under …
