Datagram Transport Layer Security (DTLS)

Datagram Transport Layer Security (DTLS) is a security protocol designed to protect data transmitted over connectionless networks, like the internet. It ensures that messages are encrypted, authentic, and cannot be tampered with, even when sent via quick, small packets called datagrams. DTLS is often used in real-time applications such as video calls, online gaming, and VoIP, where low latency is critical. It provides privacy and security without delaying the communication, enabling safe and efficient data exchange in environments where traditional connection-based security methods aren’t suitable.
