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

Where does this image take you? A visual tale from a workshop on geographical imaginations

This work is authored by a group of Ph.D. students and academics who attended a workshop on visual methodologies in the framework of the Scuola di alta formazione in geografia organised by AGeI (Association of Italian Geographers), 2022 edition. By visually reporting the workshop activities we aim at reflecting on the creative power of images in expanding geographical imaginations and its potential in the teaching of geography. The paper is shaped as a visual essay in which images and text do not refer directly to each other but rather aim at creating an imaginative reading flow
