The https://www.rfc-editor.org/rfc/rfc5246#section-7.4.9 states which messages are included for PRF computation that is included in Finished messages
It is clear for 'regular' (initial) handshake
But assume that the client wants to resume the DTLS session
Client sends the ClientHello with previous SessionID field
The server responds with ServerHello, sends ChangeCipherSpec (not included for verify_data computation) and Finished
Which messages should be included for verify_data field computation in Finished message sent from server?
A. Should it be only the most recent (resuming) ClientHello and ServerHello
B. Should it be the most recent (resuming) ClientHello and ServerHello plus previous (initial in our example) handshake messages?
