This paper presents Prio, a privacy-preserving system for the collection of aggregate
statistics. Each Prio client holds a private data value (eg, its current location), and a small set …

Timed-release encryption is a kind of encryption scheme in which a recipient can decrypt
only after a specified amount of time T (assuming that we have a moderately precise …

Consider an abstract storage device Σ(G) that can hold a single element x from a fixed,
publicly known finite group G. Storage is private in the sense that an adversary does not …

We present Whisper, a system for privacy-preserving collection of aggregate statistics. Like
prior systems, a Whisper deployment consists of a small set of non-colluding servers; these …

Quantum Anonymous Private Information Retrieval (QAPIR) allows a user to retrieve an item
from a database anonymously thus achieving better user privacy. Recently, Khan et al …

Algebraic manipulation detection codes are a cryptographic primitive that was introduced by
Cramer et al.(Eurocrypt 2008). It encompasses several methods that were previously used in …

Anonymity in networked communication is vital for many privacy-preserving tasks. Secure
key distribution alone is insufficient for high-security communications. Often, knowing who …

Conference key agreement (CKA) is a cryptographic effort of multiple parties to establish a
shared secret key. In future quantum networks, generating secret keys in an anonymous way …

Anonymous voting is a voting method of hiding the link between a vote and a voter, the
context of which ranges from governmental elections to decision making in small groups like …

Users of quantum networks can securely communicate via so-called (quantum) conference
key agreement—making their identities publicly known. In certain circumstances, however …
