Watch a 29-minute technical presentation exploring the performance implications of post-quantum cryptography (PQC) algorithms in mutual TLS (mTLS) authentication scenarios. Examine experimental results measuring Time-to-Last-Byte (TTLB) when implementing ML-KEM and ML-DSA algorithms in both client and server certificate chains. Learn how factors like network bandwidth, TCP initial congestion windows, and data transfer sizes affect connection performance in Zero Trust Architectures using mTLS. Compare these findings with previous studies focused solely on server-side PQC implementations, and discover which mTLS use cases may face greater performance impacts along with potential optimization strategies. Delivered by AWS Applied Scientists Mila Anastasova and Panos Kampanakis, this presentation fills a research gap by specifically analyzing the bidirectional authentication challenges introduced by post-quantum cryptography in mTLS environments.
