Security analysis of quantum multi-signature protocol based on teleportation

Security analysis of quantum multi-signature protocol based on teleportation The security of the recent quantum multi-signature protocol based on teleportation is analyzed. We show that there are some security vulnerabilities in the protocol. The detailed attack strategies are described from the aspect of participant attack. We also point out that the protocol is not secure against external attack. Finally, we give some possible countermeasures to improve the protocol. Quantum Information Processing Springer Journals
