    As an important part of earthquake early warning(EEW)systems,the EEW service system is the key protection target and object of network security.Given the wide impact of EEW information, ensuring its authenticity, integrity, and high timeliness is necessary. Therefore,a tamper proof framework for EEW service systems based on domestic cryptographic algorithms is designed in this study. The digital certificate and cosignature technique were used to optimize the verification process of identity authentication and message integrity,thus minimizing time consumption by the cryptographic algorithm.After the design was completed, the time consumed by the above operations was less than 0.2s, considering the safety and high timeliness of EEW information.
