mmTLS - Scaling the Performance of Encrypted Network Traffic Inspection

Explore a groundbreaking conference talk from USENIX ATC '24 that delves into mmTLS, a scalable TLS middlebox development framework designed to enhance encrypted network traffic inspection performance. Learn how researchers from Seoul National University, KAIST, and Virginia Tech address the computational challenges faced by modern network monitoring TLS middleboxes. Discover the innovative approach of mmTLS, which eliminates traffic relaying costs through secure session key sharing, maintaining end-to-end TLS properties while significantly improving throughput. Gain insights into the implementation of a private tag system for detecting illegal content modification and its minimal overhead impact. Examine the impressive performance gains achieved by mmTLS, outperforming traditional TLS proxies by factors of 2.7 to 41.2 and reaching traffic relaying throughput of 179 Gbps. This 20-minute presentation offers valuable knowledge for network security professionals, developers, and researchers interested in advancing encrypted traffic inspection techniques.
