Building Unclonable Cryptography: A Tale of Two No-cloning Paradigms

ePrint Report: Building Unclonable Cryptography: A Tale of Two No-cloning Paradigms

Ghada Almashaqbeh, Rohit Chatterjee

Unclonable cryptography builds primitives that enjoy some form of unclonability, such as quantum money, software copy protection, and bounded execution programs. These are impossible in the classical model as classical data is inherently clonable. Quantum computing, with its no-cloning principle, offers a solution. However, it is not enough to realize bounded execution programs; these require one-time memory devices that self-destruct after a single data retrieval …
