| Abstract: | Public key cryptography based on identity simplifies key management certificates. The current identity-based digital signature public key encryption has become a research hot spot. Security is an important factor in building identity-based digital signature scheme. The signature based on identity is introduced. The program model and the security model are given. This model can be used in practice to establish safe and efficient digital signature scheme. |
