DTLS is a protocol that provides security guarantees to Internet communications. It can operate on top of both TCP and UDP transport protocols. Thus, it is particularly suited for peer-to-peer and distributed multimedia applications. The same holds if the endpoints are mobile devices. In this scenario, mechanisms are needed to surmount possible network disconnections, often arising due to the mobility or the scarce resources of devices, that can jeopardize the quality of the communications. Session resumption is thus a main issue to deal with. To this aim, we propose a fast reconnection scheme that employs non-connected sockets to quickly resume DTLS communication sessions. The proposed scheme is assessed in a performance evaluation that confirms its viability.

用于移动通信的 DTLS 中的快速会话恢复

DTLS 是一种为 Internet 通信提供安全保证的协议。它可以在 TCP 和 UDP 传输协议之上运行。因此，它特别适用于对等和分布式多媒体应用程序。如果端点是移动设备，同样如此。在这种情况下，需要机制来克服可能的网络断开连接，这通常是由于设备的移动性或稀缺资源而引起的，这可能会危及通信质量。因此，会话恢复是一个需要处理的主要问题。为此，我们提出了一种快速重新连接方案，该方案采用非连接套接字来快速恢复 DTLS 通信会话。提议的计划在确认其可行性的绩效评估中进行评估。
