DTLS (Datagram Transport Layer Security)

DTLS (Datagram Transport Layer Security) is a security protocol that protects data sent over connectionless communication networks, like the internet. It ensures that data exchanged between devices—such as IoT gadgets, online gaming, or voice calls—is encrypted, authentic, and tamper-proof, even when sent quickly and unpredictably. Essentially, DTLS provides privacy and security for real-time, small data packets without slowing down transmission, making it ideal for applications requiring fast, secure communication over unreliable or lossy networks.
