Post-Quantum Digital Signatures for Enhanced Medical Image Security

Abstract

Traditional encryption methods face significant challenges due to the rapid advancement of quantum computing, necessitating the use of quantum-resistant solutions. Cryptographic hash functions are used by Sphincs+, a stateless hash-based digital signature technique, to provide robust protection against quantum attacks. This research investigates the application of Sphincs+, alongside Dilithium and Falcon, to enhance the security of medical images, which are critical for diagnostic and therapeutic processes in healthcare. By utilising digital signatures for authentication and integrity verification, Sphincs+ mitigates risks associated with unauthorised tampering and data manipulation. The integration of Sphincs+ into medical imaging frameworks strengthens data security, ensuring long-term resilience against quantum-enabled threats while maintaining the reliability of healthcare records.
