- Abstract
The cryptanalysis about enhancement on the quantum blind signature based on two-state vector formalism is further researched. A special attack strategy is put forward. In this strategy, the dishonest signer Bob only need make two measurements in the Z-basis. It is shown that he can illegally reveal 25 % of the secret key and message of the blind signature requester.
