In this letter, we show that Fan-Chen-Yeh's blind signature scheme and Chien-Jan-Tseng's partially blind signature scheme are vulnerable to the chosen-plaintext attack. We also show that both schemes can be modified so that the chosen-plaintext attack is impossible. But, still Chien-Jan-Tseng's partially blind signature scheme is vulnerable. It fails to satisfy the partial blindness property.
