TCPLS : integrating TCP and TLS

The Transmission Control Protocol (TCP) is one of the most important Internet protocols. These days, TCP is rarely used without TLS.

TCP and TLS are independant protocols and TLS makes very few assumptions on the service provided by the underlying TCP implementation. This layering separation allows one TLS implementation to be easily adapted to various TCP implementations

TCP over TLS

TCPLS takes a different approach. Since both TCP and TLS are often used together, we reconsider their interactions and design a protocol that uses the features from one protocol to improve the other.

TCPLS

TCPLS is a work in progress. We are continuously developing the prototype and will publish new use cases and experiments in the coming weeks on this website.
