Improving the security of quantum exam against cheating
Fei Gao, Qiao-Yan Wen, Fu-Chen Zhu
Abstract
The security of quantum exam [Phys. Lett. A 350 (2006) 174] is analyzed and it is found that this protocol is secure for any eavesdropper except for the "students" who take part in the exam. Specifically, any student can steal other examinees' solutions and then cheat in the exam. Furthermore, a possible improvement of this protocol is presented.
