Hi Simon, I don't think we specified a concrete recommendation, but I think the answer is probably no. The reason is that:
(a) a resumed handshake is very cheap, so it's not really saving CPU (b) the server's first flight is small in resumption, so amplification isn't much of an issue. Maybe I'm missing something though. -Ekr On Wed, Oct 3, 2018 at 7:05 AM Simon Bernard <cont...@simonbernard.eu> wrote: > Hi, > > In DTLS 1.2 over UDP, I would like to know what is the > recommendation about using HELLO_VERIFY_REQUEST during an abbreviated > handshake. > > Should we send it all the time ? or could we avoid to send it if > SESSION ID is known ? > > Thx, > > > Simon > > _______________________________________________ > TLS mailing list > TLS@ietf.org > https://www.ietf.org/mailman/listinfo/tls >
