Secure Opportunistic Multipath Key Exchange
Explore a groundbreaking key exchange protocol, Secure Multipath Key Exchange (SMKEX), in this 28-minute conference talk presented at the Association for Computing Machinery (ACM). Delve into the benefits of opportunistic encryption and learn how SMKEX provides proven protection against certain active attackers without relying on trusted third parties or pre-established secrets. Examine the main issues in authenticating key exchanges and discover how SMKEX leverages multiple public channels to enhance security. Gain insights into the attacker model, protocol implementation, and real-world applications through a measurement study. Investigate the enforcement of A/A scenarios via long-term tunnels and understand the potential impact of SMKEX on Internet communication security.
