This paper presents a condensed system architecture for a file transfer solution that leverages post quantum cryptography and blockchain to secure data against quantum threats. The architecture integrates NIST standardized algorithms CRYSTALS Kyber for encryption and CRYSTALS Dilithium for digital signatures with an immutable blockchain ledger to provide an auditable, decentralized storage mechanism. The system is modular, comprising a Sender module for secure encryption and signing, a central User Storage module for decryption, reencryption, and blockchain logging, and a Requestor module for authenticated data access. We include detailed pseudocode, analyze security risks, and offer performance insights to demonstrate the system's robustness, scalability, and transparency. learn more on arXiv
