DTLS is an implementation of TLS over UDP (a datagram protocol). per wikipedia, TLS uses TCP, and DTLS uses UDP, so all the classic differences apply. UDP communications exist as streams of packets with no ordering, delivery reliability, or flow control. applications that use datagram protocols need to make sure they can handle these concerns ...

2016年11月24日 · TLS Session resumption can avoid the public key-exchange part of the handshake, as well as the certificate verification. HTTP keep-alives will keep the socket open, same as http, but has more savings when the socket is TLS. SSL compression support is starting to show up server side, but AFAIK, most browsers aren't implementing this yet ...

2017年1月10日 · It would probably fit better on security.SX which covers SSL/TLS extensively, and DTLS some, although not SCTP that I can recall. TLS assumes and requires the service provided by TCP, namely a (single) in-sequence octet stream, where data is delivered in order without loss or duplication or reordering, unless the connection fails in which case ...

2020年9月25日 · It doesn't depend on DTLS or TLS, if a self-signed certificate is trusted/accepted. This depends only from the peer's trusted certificates. If the client's or server's certificate path/chain contains a certificate, which signature could be verified by a trusted certificate, then it's assumed to be trusted.

2019年9月17日 · scapy-ssl_tls support has very basic support for DTLS. What is probably going wrong here is that you are not setting the correct lengths for the ClientHello, CipherSuites and HandShake. You also need to make sure you're setting the correct fragment length.

From Microsoft: There is no documentation for implementing DTLS using Schannel. Known and persistent doc gap. There are a few differences, but a TLS client or server can be adapted to DTLS fairly easily (a number of customers have done this successfully). Set SCHANNEL_CRED.grbitEnabledProtocols to SP_PROT_DTLS1_X.

2020年11月12日 · I recently discovered DTLS, however can't seem to find any Android libraries or APIs for its use akin to what SSLSocket is for TLS/SSL. I'm fairly new to Android dev, so any tutorials or posts would also be super helpful :)

2014年2月7日 · DTLS provides its own fragmentation mechanism for the handshake messages, it takes care of reordered packets too (has a frag offset/len fields in the handshake message header). This helps the dtls send packets greater than …

2013年9月11日 · What is the Major difference in SNMP over DTLS and SNMPv3 USM model, which one to prefer. TLS and DTLS make use of the Transport Security Model (TSM) security model, defined in RFC5591 which was created as an alternative to the USM security model

2020年7月8日 · If you read DTLS - RFC 6347, you will read, that it contains a lot of counter measures for UDP usage. It also explains, why using TLS (with its inherent assumption) will not work for UDP. If DTLS over TCP would makes sense, depends mostly from your expectations. So why would you like to do that?
