Class ChangeCipherSpecMessage

java.lang.Object

org.eclipse.californium.scandium.dtls.AbstractMessage

org.eclipse.californium.scandium.dtls.ChangeCipherSpecMessage

All Implemented Interfaces:

DTLSMessage

public final class ChangeCipherSpecMessage
extends AbstractMessage

The change cipher spec protocol exists to signal transitions in ciphering strategies. The protocol consists of a single message, which is encrypted and compressed under the current (not the pending) connection state. The ChangeCipherSpec message is sent by both the client and the server to notify the receiving party that subsequent records will be protected under the newly negotiated CipherSpec and keys. For further details see RFC 5246.
