Contract Signature Using Quantum Information
Paulo Benicio Melo de Sousa, Rubens Viana Ramos
Abstract
This paper describes how to perform contract signature in a fair way using quantum information. The protocol proposed permits two partners, users of a communication network, to perform a contract signature based on the RSA security. The authentication of the signers is based on the use of a non-local XOR function of two classical bits.
