Improving the security of quantum exam against cheating

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.
