Keyless secrecy against bounded adversaries
Anne Broadbent, Upendra Kapshikar, Denis Rochette
We introduce a keyless coding/cryptographic primitive that asks for two guarantees at once: the receiver is never fooled into accepting a message other than the one sent, and the a…

Optimal Untelegraphable Encryption and Implications for Uncloneable Encryption
Anne Broadbent, Eric Culf, Denis Rochette
We investigate the notion of untelegraphable encryption (UTE), a quantum encryption primitive that is a special case of uncloneable encryption (UE), where the adversary's capabilit…

Towards Universal Quantum Tamper Detection
Anne Broadbent, Upendra Kapshikar, Denis Rochette
Tamper-resilient cryptography studies how to protect data against adversaries who can physically manipulate codewords before they are decoded. The notion of tamper detection codes…
