Secure Online Voting System Using Hybrid Post-Quantum Signatures

This work introduces a secure online voting system designed to withstand potential quantum threats. It combines Merkle Trees, Lamport Signatures, and the SHA-256 hash function to secure the system's cryptographic infrastructure. Merkle Trees are employed for efficient data integrity verification, ensuring the reliability of transmitted information. Lamport Signatures, known for their resistance to quantum attacks, contribute to authentication mechanisms, adding an extra layer of security to the voting process. The utilization of the SHA-256 hash function further enhances the system against potential quantum vulnerabilities. The integration of Lamport Signatures with the Merkle Trees facilitates a secure verification process. This enables rapid checks for vote integrity, providing a defense against tampering or malicious interference. The goal of this work is to establish a secure online voting platform that upholds the principles of confidentiality, integrity, and authenticity. By adhering to the highest security standards in the field, the proposed system ensures a trustworthy environment for the electoral process, even in the face of emerging quantum threats.
