HORNET: High-speed Onion Routing at the Network Layer

Chen Chen, Daniele Enrico Asoni, David Barrera, George Danezis, Adrian Perrig

Abstract

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.

    • LN is an onion routed network, and has some privacy - notably, sender privacy, as the sender does not need to be known to the recipient. The recipient however is not private, but there have been proposals for rendevouz routing which could also anonymize them. LN payments are…

    • I am looking forward to Hornet[0]. The authors haven't put a PoC out yet. It is described decently in a recent mailing list post[1] (and impl[2]) on a BitCoin decentralizing project. A quality project might take the speed of the Hornet protocol, the tor hidden services approach…
