In information technology, the Datagram Transport Layer Security (DTLS) communications protocol provides communications security for datagram protocols. DTLS allows datagram-based applications to communicate in a way that is designed〔RFC 4347〕〔RFC 6347〕 to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees. The DTLS protocol datagram preserves the semantics of the underlying transport — the application does not suffer from the delays associated with stream protocols, but has to deal with packet reordering, loss of datagram and data larger than the size of a datagram network packet. ==Definition== The following documents define DTLS: * RFC 6347 for use with User Datagram Protocol (UDP), * RFC 5238 for use with Datagram Congestion Control Protocol (DCCP), * RFC 6083 for use with Stream Control Transmission Protocol (SCTP) encapsulation, * RFC 5764 for use with Secure Real-time Transport Protocol (SRTP) subsequently called DTLS-SRTP in a draft with Secure Real-Time Transport Control Protocol (SRTCP). DTLS 1.0 is based on TLS 1.1, and DTLS 1.2 is based on TLS 1.2. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Datagram Transport Layer Security」の詳細全文を読む スポンサード リンク
