In order to overcoming key-escrow problem of ID-based cryptosystem and public key replacing problem of certificateless cryptosystem,researcher proposed the definition of certificate-based cryptosystem. This paper analyzed the certificatebased signature scheme by Li Zhi-min et al. The result showed that it couldn't meet the safe requirement of unforgeability. It analyzed a certificate-based blind signature scheme by Huang Ru-fen et al. The result indicated that it was not security by replacing public key attack. It analyzed an ID-based partially blind signature scheme by He Jun-jie et al. The result indicated that it didn't resist the changing agreed information attack.
