| 520 | 3 | |a Post-TCP transport protocols such as QUIC now include end-to-end encryption at the transport layer. This enhances security by making their packets opaque to connection-splitting proxies and immune to ossification, but can harm performance. In this dissertation, I will present the Sidekick protocol approach to in-network assistance for secure transport protocols, where proxies and endpoints send information on an adjacent connection about which encrypted packets they have received. Sidekick protocols apply set reconciliation techniques in a novel setting to efficiently refer to encrypted packets in a quACK, without using plaintext sequence numbers. In some use cases of the Sidekick protocol, Packrat proxies keep a small cache of packets for possible in-network retransmissions of encrypted packets. This approach allows secure transport protocols to achieve performance benefits similar to those of traditional PEPs, but leaves the protocol unchanged on the wire and free to evolve. Finally, I will present the split throughput heuristic for reasoning about connection-splitting in the context of two recent developments: the BBR congestion control algorithm and the QUIC transport protocol. I use this heuristic in an emulation measurement study and discuss how connection-splitting, despite the ossification it can induce, still offers valuable performance benefits today. | |
