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

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

Secure multi-party computation (MPC) allows multiple parties to compute a known function
over inputs held by each party, without any party having to reveal its private input …

Broadcasting information anonymously becomes more difficult as surveillance technology
