Abstract
Quantum-level cryptography of delegated digital signatures. By implementing quantum-level computing principles, delegate signatures are provided that are unclonable, unforgeable and can not be repudiate. Specifically, at least four quantum particles are entangled, with one particle assigned to each of a third-party verification entity, a signature delegate, a delegatory signature authorizer entity and a signature requester entity. In addition, Bell State measurements (BSMs) are performed at the signature delegate, the delegatory signature authorizer entity and the third-party verification entity to allow the original signer (i.e., the signature delegator) to securely delegate signature to a signature delegate and perform an event, such as a payment process or the like.
