The DatagramTransport Layer SecurityProtocol (DTLS) is a widely used security protocol for securing network traffic in mesh networks
. The DTLS protocol can be considered as " TLS
over Datagram Transport", because the TLS protocol cannot be used directly in datagram networks. DTLS supports data protection when communicating with datagram protocols such as the User Datagram Protocol (UDP) and prevents eavesdropping, manipulation or tampering of client-server applications. The DTLS protocol is based on the TLS protocol, Transport Layer Security (TLS), and provides comparable security.
