Secure Channels and Termination: The Last Word on TLS.

Secure channels are one of the most pivotal building blocks of cryptography today. Internet connections, secure messaging, protected IoT data, etc., all rely upon the security of the underlying channel. In this work we define channel protocols, as well as security for channels constructed from stateful length-hiding authenticated encryption (stLHAE) schemes. Furthermore, we initiate the concept of secure termination where, upon receipt of a...
