The Transport Layer Security (TLS) Working Group of the IETF has taken on the task of specifying a new version of the TLS protocol. There have been a number of attacks against TLS reported in the last few years: Renegotiation Attack, BEAST, CRIME, BREACH, RC4 Attack, Lucky Thirteen, Truncation Attack, and Triple Handshake Attack. TLS 1.3 will be designed to address these issues and to remove features no longer needed. In addition, the protocol will be designed to allow for a ‘1 round trip time’ (1-RTT) handshake.
