Abstract :
We point out that the quantum digital signature scheme proposed in ICACT 2005 has three problems. According to the original description of the scheme, we find: (1) the quantum one-way function is not specified clearly; (2) the signer Alice does not use her private key in the signing process; (3) both the signing and the verification can not work well.
