Indistinguishability and semantic security for quantum encryption scheme
Chong Xiang, Li Yang
We investigate the definition of security for encryption scheme in quantum context. We systematically define the indistinguishability and semantic security for quantum public-key a…
The Classification of Quantum Symmetric-Key Encryption Protocols
Chong Xiang, Li Yang, Yong Peng +1
The classification of quantum symmetric-key encryption protocol is presented. According to five elements of a quantum symmetric-key encryption protocol: plaintext, ciphertext, key,…
Quantum probabilistic encryption scheme based on conjugate coding
Li Yang, Chong Xiang, Bao Li
We present a quantum probabilistic encryption algorithm for a private-key encryption scheme based on conjugate coding of the qubit string. A probabilistic encryption algorithm is g…
Unicity Distance of Quantum Encryption Protocols
Chong Xiang, Li Yang
Shannon presented the concept `unicity distance' for describing the security of secret key encryption protocols against various ciphertext-only attacks. We develop this important c…
Quantum Public-Key Encryption Schemes Based on Conjugate Coding
Li Yang, Biyao Yang, Chong Xiang
We present several quantum public-key encryption (QPKE) protocols designed with conjugate coding single-photon string, thus may be realized in laboratory with nowadays techniques.…
Qubit-string-based bit commitment protocols with physical security
Li Yang, Chong Xiang, Bao Li
Several kinds of qubit-string-based(QS-based) bit commitment protocols are presented, and a definition of information-theoretic concealing is given. All the protocols presented her…
