The reliance on asymmetric public key cryptography (PKC) and symmetric encryption for cyber-security in current telecommunication networks is threatened by the emergence of powerful quantum computing technology. This due to ability computers efficiently solve problems such as factorization or discrete logarithms, which are basis classical PKC schemes. Thus, assumption that communications secure no longer holds true. Quantum Key Distribution (QKD) post-quantum (PQC) first technologies allow resist attacks a computer. To achieve quantum-resistant communications, aforementioned need be incorporated into network security protocol Transport Layer Security (TLS). In this paper, we describe implement two novel, hybrid solutions QKD PQC combined inside TLS achieving authenticated exchange: Concatenation Exclusively-OR (XOR). We present results, terms complexity enhancement, integrating state-of-the-art practical, industry-ready implementation. Our findings demonstrate adoption PQC-only approach enhances handshake performance approximately 9 % compared methods. Furthermore, our PQC-QKD comes at cost 117 during establishment process. return, substantially augment handshake, paving road development future-proof communication systems based PQC.
