Fast-Track Session Establishment for TLS

We describe a new, ``fast-track'' handshake mechanism for TLS. A fast-track client caches a server's public parameters and certain client-server negotiated parameters in the course of an initial, enabling handshake; these need not be resent on subsequent, fast-track ones. The new mechanism reduces both network traffic and flows, and requires no additional server state. The network savings are particularly relevant to wireless, bandwidth-limited devices.
