The Internet Engineering Task Force adopted the DNS over HTTPS protocol in 2018 to
remediate privacy issues regarding the plain text transmission of the DNS protocol …

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 …

Abstract In Private Information Retrieval (PIR), a client wishes to retrieve the value of an
index i from a public database of N values without leaking any information about i. In their …

Although the security benefits of domain name encryption technologies such as DNS over
TLS (DoT), DNS over HTTPS (DoH), and Encrypted Client Hello (ECH) are clear, their …

Many systems today distribute trust across multiple parties such that the system provides
certain security properties if a subset of the parties are honest. In the past few years, we …

The three decade struggle to ensure Internet data confidentiality---a key aspect of
communications privacy---is finally behind us. Encryption is fast, secure, and standard in all …

Website fingerprinting (WF) is a well-known threat to users' web privacy. New Internet
standards, such as QUIC, include padding to support defenses against WF. Previous work …

Public key cryptography is used to asymmetrically establish keys, authenticate or encrypt
data between communicating parties at a relatively high performance cost. To reduce …

Abstract In Private Information Retrieval (PIR), a client wishes to access an index i from a
public n-bit database without revealing any information about i. Recently, a series of works …

We propose a new unified framework to construct multi-server, information-theoretic Private
Information Retrieval (PIR) schemes that leverage global preprocesing to achieve sublinear …
