Participant attack on quantum secret sharing based on entanglement swapping被引量：4
《Chinese Physics B》2009年第4期1333-1337,共5页宋婷婷 张劼 高飞 温巧燕 朱甫臣 
Project supported by the National High Technology Research and Development Program of China (Grant No 2006AA01Z419);the Major Research Plan of the National Natural Science Foundation of China (Grant Nos 90604023, 60873191 and 60821001);the National Laboratory for Modern Communications Science Foundation of China (Grant No 9140C1101010601);the Natural Science Foundation of Beijing, China (Grant No 4072020);the Integrated Service Network Open Foundation
The security of quantum secret sharing based on entanglement swapping is revisited and a participant attack is presented. In this attack two dishonest agents together can illegally recover the secret quantum state wit...
