Ronny Döring, Marc Geitz · NOMS 2022-2022 IEEE/IFIP Network Operations and Management Symposium · 2022
With the increasing speed in the development of quantum computers, secure communication is at risk. A promising candidate to replace existing cryptographic patterns with quantum-secure variants is Post-Quantum Cryptography (PQC). This paper presents an empirical analysis of how Post-Quantum Cryptography affects real-world performance compared to classical cryptography. Therefore we analyze the Transport Layer Security (TLS) handshake performance showing that Post-Quantum Cryptography can be as fast or even faster than classical cryptography, depending on the specific encryption and signature algorithms used.
