| Abstract: | The security of quantum secret sharing based on entanglementswapping is revisited and a participant attack is presented. In thisattack two dishonest agents together can illegally recover thesecret quantum state without the help of any other controller, andit will not be detected by any other users. Furthermore, bymodifying the distribution process of particles and adding adetection step after each distribution process, we propose animproved protocol which can resist this kind of attack. |
