A note on quantum McEliece public-key cryptosystem
Li Yang, Min Liang
Inspired by Fujita's analysis [Quantum inf. & comput. 12(3&4), 2012], we suggest a twice-encryption scheme to improve the security of the original quantum McEliece public-key encry…
Cryptography based on operator theory (I): quantum no-key protocols
Li Yang, Min Liang
We study cryptography based on operator theory, and propose quantum no-key (QNK) protocols from the perspective of operator theory, then present a framework of QNK protocols. The f…
Quantum public-key algorithms to encrypt and authenticate quantum messages with information-theoretic security
Min Liang, Li Yang
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 qu…
On Quantum Turing Machine Halting Deterministically
Min Liang, Li Yang
We define a subclass of quantum Turing machine (QTM) named SR-QTM, which halts deterministically and has deterministic tape head position. A quantum state transition diagram (QSTD)…
