資料包傳輸層安全

(重定向自DTLS

資料包傳輸層安全(英語:Datagram Transport Layer Security,縮寫為 DTLS),又譯數據包傳輸層安全,是一種通訊協定,它向基于数据报的应用提供傳送安全性,使应用能以一种防止窃听、篡改、伪造的方式[1][2]通信。DTLS协议基于面向字串流TLS协议,意在提供類似的安全保護。DTLS常用於串流媒體。由于DTLS采用UDP或SCTP而不是TCP,它能在用于创建VPN通道时避免“TCP熔断问题”。[3][4]

定義

下列文档定义DTLS:

DTLS 1.0的底層為TLS 1.1,DTLS 1.2的底層為TLS 1.2,DTLS 1.3的底層為TLS 1.3。DTLS 1.1并不存在,为了与TLS版本编号相协调,这个版本编号略过了。[2]就像前期的DTLS版本一样,DTLS 1.3意在提供“[与TLS 1.3]等价的安全性保证,除顺序保护/不可重放性”。[6]
