Transport Layer Security is a cryptographic protocol that is designed to provide security for communication over the internet between a client and server. It is meant to ensure the safe delivery of data between a client and server, but it does NOT account for security at …

ssl - Difference between DTLS and TLS - Stack Overflow 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 Why does TLS require TCP? - Information Security Stack TLS does not require TCP, it only requires a reliable transport. There is even a standard for TLS over SCTP which is another reliable transport protocol.. But, if you take today's internet then you usually only have UDP and TCP as transport protocols on top of IP and from these two TCP is the only reliable one. tls - Is HTTPS over UDP secure? - Information Security Just like UDP, TCP is easy to spoof and manipulate. TCP is only to make things more reliable, not more secure. With UDP, packets can be doubled, missed or sent in the wrong order. TLS is a means to fix these issues. TLS works on UDP instead of TCP.

What is DTLS (Datagram Transport Layer Security)?

UDP and TCP protocols come into play with VoIP because they structure the way web traffic travels through the Internet. TCP and UDP packets are sent from a source to your phone or computer, and if any of these packets are dropped, it will affect the quality of your call. SSL/TLS typically runs on top of TCP, but there is nothing to stop you from running it on UDP, SCTP or any other transport layer protocol. As a matter of fact HTTPS over TCP and UDP are both defined as "well known" by IANA and have reserved port numbers. This document describes the Heartbeat Extension for the Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) protocol. The Heartbeat Extension provides a new protocol for TLS/DTLS allowing the usage of keep-alive functionality without performing a renegotiation and a basis for path maximum transmission unit (PMTU) discovery for DTLS.
