Transport Layer Security (TLS) is used for securing everything from Web transactions (HTTPS) to voice and video calls (DTLS-SRTP). However, the basic design of TLS dates back to the mid 1990s and the protocol is starting to show its age: TLS contains a number of features which no longer seem desirable and recent analytic work has discovered a number of protocol vulnerabilities (Triple Handshake, Logjam, etc.). In addition, as cryptographic algorithms have gotten faster, handshake latency has become a higher priority and TLS's current handshake does not reflect the state of the art.
In order to address these issues, the IETF TLS Working Group is currently developing a major revision of TLS, dubbed "TLS 1.3". TLS 1.3 has five major objectives:
In this talk, we will cover the TLS 1.3 protocol itself, its design process, and current status.
