NDSS 2020 Post-Quantum Authentication in TLS 1.3: A Performance Study

SESSION 10B-2 Post-Quantum Authentication in TLS 1.3: A Performance Study The potential development of large-scale quantum computers is raising concerns among IT and security research professionals due to their ability to solve (elliptic curve) discrete logarithm and integer factorization problems in polynomial time. There is, therefore, a threat to public-key cryptography as all the currently used algorithms would be deemed insecure in a post-quantum (PQ) setting. In response, the National Institute of Standards and Technology (NIST) has initiated a process to standardize quantum-resistant crypto algorithms, focusing primarily on their security guarantees. Since PQ algorithms present significant differences over classical ones, their overall assessment should not be performed out-of-context. This work presents a detailed performance evaluation of the NIST signature algorithm candidates and investigates the imposed latency on TLS 1.3 connection establishment under realistic network conditions. In addition, we investigate their impact on the achievable TLS session throughput of a server and analyze the trade-off between lengthier PQ signatures, and computationally heavier PQ cryptographic operations for idle and heavily loaded servers. Our results demonstrate that the adoption of at least two PQ signature algorithms would indeed be viable for time-sensitive applications over TLS with little additional overhead over current signature algorithms. Also, we argue that more of the NIST PQ candidates can effectively be used for less time-sensitive applications, and provide an in-depth discussion on the integration of PQ authentication in encrypted tunneling protocols, along with the related challenges, and alternatives. Finally, we propose and evaluate the combination of different PQ signature algorithms across the same certificate chain in TLS. Results show a reduction of the TLS handshake time and a significant increase of a server's TLS tunnel connection rate over the alternative of the chain using a single PQ signature scheme.

ABOUT NDSS The Network and Distributed System Security Symposium (NDSS) fosters information exchange among researchers and practitioners of network and distributed system security. The target audience includes those interested in practical aspects of network and distributed system security, with a focus on actual system design and implementation. A major goal is to encourage and enable the Internet community to apply, deploy, and advance the state of available security technologies. https://www.ndss-symposium.org/ #NDSS #NDSS20 #NDSS2020 #InternetSecurity
