[[ddsf:public:guidebook:06_append:glossary:start| Return to Glossary ]]

**Datagram Transport Layer Security (DTLS)** is a communications [[ddsf:public:guidebook:06_append:glossary:p:protocol|protocol]] designed to protect data privacy and preventing eavesdropping and tampering. It is based on the [[ddsf:public:guidebook:06_append:glossary:t:tls]] protocol, which is a protocol that provides security to computer-based communications networks. The main difference between DTSL and TLS is that DTLS uses [[ddsf:public:guidebook:06_append:glossary:u:udp]] and [[ddsf:public:guidebook:06_append:glossary:t:tls]] uses [[ddsf:public:guidebook:06_append:glossary:t:tcp]]. It is used across web browsing, mail, instant messaging and VoIP. DTSL is one of the security protocols used for WebRTC technology along with SRTP.
