The document discusses quantum key distribution protocols (QKDPs) aimed at enhancing security in large networks by integrating quantum cryptography with classical methods. It introduces two three-party QKDPs—one with implicit and the other with explicit mutual authentication—overcoming limitations of existing systems that cannot detect passive attacks. The proposed system offers increased security against man-in-the-middle attacks, eavesdropping, and replay attacks while optimizing communication efficiency.

- 2. Abstract This work presents quantum key distribution protocols ( QKDPs ) to safeguard security in large networks, ushering in new directions in classical cryptography and quantum cryptography. Two three-party QKDPs, one with implicit user authentication and the other with explicit mutual authentication , are proposed to demonstrate the merits of the new combination.
- 3. Existing System In classical cryptography, three-party key distribution protocols utilize challenge response mechanisms or timestamps to prevent replay attacks. Classical cryptography cannot detect the existence of passive attacks such as eavesdropping.
- 4. Limitations of Existing System Identifies the security threads in the message, but not the security threads in the session key.
- 5. Proposed System The primary goal of the system is to provide the security to the users, the security is provided by using Quantum mechanisms.
- 6. Advantages of the Proposed System Security against such attacks as man-in-the-middle, eavesdropping and replay, Efficiency is improved as the proposed protocols contain the fewest number of communication rounds among existing QKDPs, and Two parties can share and use a long-term secret (repeatedly).
