Seamless Transition to Post-Quantum TLS 1.3: A Hybrid Approach Using Identity-Based Encryption
Thiago Leucz Astrizi, Ricardo Felipe Custódio · Sensors · 2024
We propose a novel solution to streamline the migration of existing Transport Layer Security (TLS) protocol implementations to a post-quantum Key Encapsulation Mechanism for Transport Layer Security (KEMTLS). By leveraging Identity-Based Encryption (IBE), our solution minimizes the necessary modifications to the surrounding infrastructure, enabling the reuse of existing keys and certificates. We provide a proof-of-concept implementation and performance analysis, demonstrating the practical feasibility and effectiveness of our proposed approach.
