Why is the DTLS (Datagram Transport Layer Security) protocol used for streaming applications that need security?
What will be an ideal response?
ANSWER: DTLS is a variant of TLS that is designed specifically for streaming communications. As the name implies, DTLS relies on UDP instead of TCP, which minimizes delays. However, applications using DTLS must provide their own means of packet reordering, flow control, and reliability assurance. DTLS includes security levels that are comparable to TLS and is commonly used by delay-sensitive applications such as VoIP and tunneling applications such as VPN.
