Multi-Party Controlled Semi-Quantum Dialogue Protocol Based on Hyperentangled Bell States

Area of Science:

• Quantum Information Science
• Computer Science

Background:

• Semi-quantum dialogue systems face resource consumption and security vulnerabilities.
• Single controlling parties are susceptible to information compromise.

Purpose of the Study:

• To propose a multi-party controlled semi-quantum dialogue protocol addressing resource and security issues.
• To enhance the security and efficiency of classical participants in quantum communication.

Main Methods:

• Utilizes hyperentangled Bell states for the protocol.
• Implements a multi-party controlled mechanism (Charlie1 to Charlie n) for distributed trust.
• Integrates adaptive Huffman compression algorithm for classical participant data transmission.
• Employs an "immediate measurement and transmission" mechanism.

Main Results:

• The protocol establishes a distributed trust model, requiring collective authorization from all controllers.
• Adaptive Huffman coding optimizes storage space complexity for classical participants.
• Information-theoretic analysis proves the protocol's resistance to common attacks and malicious controllers.
• Demonstrates high communication efficiency and lower resource consumption.

Conclusions:

• The proposed protocol effectively solves resource consumption and security vulnerabilities in semi-quantum dialogue.
• It offers robust security against untrustworthy controllers and collusion attacks.
• The integration of Huffman compression enhances classical participant efficiency and data handling.
