This paper analyzes the four-state QPKE scheme of Liu et al. and shows that its ciphertext structure leaks information about computational-basis plaintexts, and proposes sQPKE, a simple quantum public-key encryption scheme that uses only elementary operations.
We develop a new three-party quantum secret-sharing (QSS) protocol based on a three-qubit W state. This protocol encodes the secret-sequence bits using X gates and employs randomly selected Hadamard operations and measurement bases to generate information and security-test rounds. We evaluate the efficiency of the prop...
This paper proposes a dynamic quantum secure multi-party multiplication protocol with verifiable result integrity, based on homomorphic encryption, that can resist a series of typical external and internal attacks.

The proposed quantum computing leads to an important security problem in classic key exchange methods for secure file communication. In this paper, we propose a Quantum Key Distribution based secure file encryption scheme for secure storage and transmission of files which uses BB84 Quantum Key Distribution protocol alo...

A three-axis taxonomy of QSDC protocols is proposed, classifying them by quantum resource type, physical transmission channel, and device trust model, and it presents a comparative performance analysis of QKD employing a hyperchaotic cipher over QSDC channels across seven quantum image representations, showing that QKD...

Pseudorandom permutations are ubiquitous in theoretical and applied cryptography. PRPs that offer security even against adversaries making quantum queries are of increasing interest, and used in applications ranging from constructing pseudorandom unitaries to separating SZK from BQP. A successful framework for construc...

Hamming Quasi-Cyclic (HQC) has been selected by NIST as a standard for code-based Post-Quantum Cryptography (PQC) Key Encapsulation Mechanisms (KEMs). While HQC offers robust theoretical security based on the Decisional Quasi- Cyclic Syndrome Decoding problem, its physical implementation is vulnerable to side-channel a...
