Abstract

Reducing the amount of information exchanged during a Transport Layer Security handshake to a minimum helps to improve performance in environments where devices are connected to a network with a low bandwidth and lossy radio technology. With the Internet of Things, such environments exist, for example, when devices use IEEE 802.15.4, Bluetooth Low Energy, or low power wide area networks. For more information about the challenges with smart object deployments, please see [RFC6574].

       Transport Layer Security (TLS) Cached Information Extension

Abstract

   Transport Layer Security (TLS) handshakes often include fairly static    information, such as the server certificate and a list of trusted    certification authorities (CAs).  This information can be of    considerable size, particularly if the server certificate is bundled    with a complete certificate chain (i.e., the certificates of    intermediate CAs up to the root CA).

   This document defines an extension that allows a TLS client to inform    a server of cached information, thereby enabling the server to omit    already available information.
