Abstract

The Stream Control Transmission Protocol (SCTP) uses a 32-bit checksum in the common header of each packet to provide some level of data integrity. If another method used by SCTP already provides the same or a higher level of data integrity, computing this checksum does not provide any additional protection but does consume computing resources.

This document provides a simple extension allowing SCTP to save these computing resources by using zero as the checksum in a backwards-compatible way. It also defines how this feature can be used when SCTP packets are encapsulated in Datagram Transport Layer Security (DTLS) packets.
