The first SCION book, published in 2017, summarized the results of eight years of work by
over a dozen researchers. Now, five years later, we have completely rewritten the book. It …

IPv6 is being more and more adopted, in part to facilitate the millions of smart devices that
have already been installed at home. Unfortunately, we find that the privacy of a substantial …

We present IPvSeeYou, a privacy attack that permits a remote and unprivileged adversary to
physically geolocate many residential IPv6 hosts and networks with street-level precision …

The Internet use IP addresses to identify and locate network interfaces of connected devices.
IPv4 was introduced more than 40 years ago and specifies 32-bit addresses. As the Internet …

We describe protocol features to provide both Identity Privacy and Location Privacy at the
network layer that are truly end-to-end, strengthening the trust model by constraining the …

As more network communication is encrypted to provide data privacy for users, attackers are
focusing their attention on traffic analysis methods for side-channel attacks on user privacy …

In constrained IoT networks, Stateless Address Autoconfiguration (SLAAC) utilizes the
Duplicate Address Detection (DAD) protocol to ensure the uniqueness of IPv6 addresses …

Format-Preserving Encryption (FPE) algorithms are symmetric cryptographic algorithms that
encrypt an arbitrary-length plaintext into a ciphertext of the same size. Standardisation …

This paper studies how to implement a privacy friendly form of ticketing for public transport in
practice. The protocols described are inspired by current (privacy invasive) public transport …

A promising feature of IPv6 is allowing devices to change their IP addresses periodically,
thereby enhancing privacy against surveillance and censorship. However, legacy …
