Design of Quantum Key Agreement Protocols with Strong Fairness Property
arXiv:1510.02353
Abstract
This study distinguishes the weak fairness property from the strong fairness property which is necessary in the quantum key agreement (QKA) and shows that most of the existing QKAs cannot achieve the strong fairness property with a key manipulation problem.To solve this problem, a model which describes the way to design a QKA with the strong fairness property is proposed. Based on the model, an example QKA is presented. Security analyses show that the proposed QKA is effective to resist not only outsider's eavesdropping attack but also insider's key manipulation.
