Abstract Based on Bell states, a new semi-quantum private comparison protocol is proposed that enables two classical users to securely compare the equality of their information with aid semi-honest third party. Different from existing protocols, participants in presented do not need measure and prepare any quantum state, which only reduces consumption devices, but also greatly improves feasibility protocol. Performing different unitary operations received particles, can secret information. Besides, devised has higher qubit efficiency than other similar counterparts, since two-bit privacy each time one qubit. Meanwhile, after completing process, all states could be reused they still retain corresponding entanglement property, facilitates recycle resources. Security analyses indicate designed scheme secure against external attack internal attack. Moreover, involved our are simulated IBM Quantum Experience demonstrate effectiveness security scheme.

Quantum private comparison (QPC) is a fundamental cryptographic protocol that allows two parties to compare the equality of their inputs without revealing any information about those each other. In recent years, QPC protocols utilizing various quantum resources have been proposed. However, these lower utilization and qubit efficiency. To address this issue, we propose an efficient based on GHZ states, which leverages unique properties states rotation operations achieve secure comparison. The secret encoded in angles performed received sequence transmitted along circular mode. This results multiplexing enhances resources. Our does not require key distribution (QKD) for sharing ensure security inputs, resulting no consumption sharing. One state can be compared three bits classical comparison, leading efficiency reaching 100%. Compared with existing protocol, our key. It also demonstrates enhanced performance

Quantum private comparison (QPC) enables two users to securely conduct comparisons in a network characterized by mutual distrust while guaranteeing the confidentiality of their inputs. Most previous QPC protocols were primarily used determine equality information between users, which constrained scalability. In this paper, we propose protocol that leverages entanglement correlation particles four-particle cluster state. This can compare groups within one execution, with each group consisting users. A semi-honest third party (TP), who will not deviate from execution or conspire any participant, is involved assisting achieve comparisons. Users encode inputs into specific angles rotational operations performed on received quantum sequence, then sent back TP. Security analysis shows both external attacks and insider threats are ineffective at stealing data. Finally, our some previously proposed protocols.

Quantum-resistant cryptography develops cryptographic protocols and algorithms that can withstand attacks from quantum computers. Quantum computers solve certain mathematical problems much faster than classical computers, making current encryption techniques like RSA ECC vulnerable to such as Shor's algorithm. To address this, quantum-resistant focuses on creating new based are difficult for efficiently. Examples include lattice-based, code-based, hash-based, multivariate polynomial cryptography. The National Institute of Standards Technology (NIST) is leading efforts standardize these ensure they compatible with various systems applications. While offer protection, may involve higher computational complexity larger key sizes compared traditional methods, posing implementation challenges ongoing research aims address.
