TLS is the most important cryptographic protocol in the internet. At CRYPTO 2012, the researcher presented the first proof of the unmodified TLS with ephemeral Diffie-Hellman key Exchange (TLS-DHE) for mutual authentication. Since TLS cannot be proven secure under the classical definition of Authenticated Key Exchange (AKE), they introduce a new security model called Authenticated and Confidential Channel Establishment (ACCE) that captures the security properties expected from TLS in practice. The authors extend this result in two ways.
