• D. DTLS-SRTP
  DTLS-SRTP is a security protocol framework that uses Datagram Transport Layer Security to negotiate keys and provide encryption and authentication for Secure Real-time Transport Protocol media streams, commonly used in VoIP and WebRTC.
• E. SRTP for secure media transport
  SRTP for secure media transport is a security protocol that encrypts and authenticates real-time audio and video streams, commonly used in VoIP and WebRTC communications.
