DTLS Client
Direction:
Client

DTLS (Datagram Transport Layer Security) protocol is used for protecting datagram based traffic between client and server applications. DTLS is founded on TLS (Transport Layer Security) being as similar to TLS as possible. However, since TLS requires reliable data channel, it have been necessary to develop a dedicated protocol for securing datagram traffic. DTLS Client Test Suite is developed for testing robustness and security of client applications utilizing DTLS protocol. Both versions 1.0 and 1.2 are supported by the test suite. The test suite supports UDP transport.
