Options for Securing RTP Sessions
The Real-time Transport Protocol (RTP) is used in a large number of
different application domains and environments. This heterogeneity
implies that different security mechanisms are needed to provide
services such as confidentiality, integrity, and source
authentication of RTP and RTP Control Protocol (RTCP) packets
suitable for the various environments. The range of solutions makes
it difficult for RTP-based application developers to pick the most
suitable mechanism. This document provides an overview of a number
of security solutions for RTP and gives guidance for developers on
how to choose the appropriate security mechanism
HORNET: High-speed Onion Routing at the Network Layer
We present HORNET, a system that enables high-speed end-to-end anonymous
channels by leveraging next generation network architectures. HORNET is
designed as a low-latency onion routing system that operates at the network
layer thus enabling a wide range of applications. Our system uses only
symmetric cryptography for data forwarding yet requires no per-flow state on
intermediate nodes. This design enables HORNET nodes to process anonymous
traffic at over 93 Gb/s. HORNET can also scale as required, adding minimal
processing overhead per additional anonymous channel. We discuss design and
implementation details, as well as a performance and security evaluation.Comment: 14 pages, 5 figure
