Post-Quantum Cryptographic Analysis Maps Vulnerability Across the Entire Network Stack

arXiv·medium signal

Comprehensive analysis showing that when a message traverses the network stack, each layer applies its own cryptographic operations with different quantum vulnerability profiles. The paper maps how message security depends on the composition of transformations across all layers — not any single algorithm — revealing that replacing one quantum-vulnerable algorithm still leaves attack surfaces at other layers. Provides a systematic quantum-readiness audit framework for practitioners managing network infrastructure.
