Abstract：Objective To upgrade the existing digital signature system to meet the needs of paperless business development in
hospitals in the next five years. Methods Using state secret algorithm, cloud signature system, electronic signature technology and
internet technology, a dual machine hot standby certificate authority (CA) identification cloud service system that spans the internal
network, security zone, and external network was established, and the cloud signature business system was integrated with the actual
medical business system. Results A set of CA identification and signature business system meeting the needs of hospital business
was established, the state secret algorithm of all CA business systems in our hospital was upgraded, over 330 USB_KEY were
upgraded, and a mobile phone login and signature service platform was built. The failure to success ratio was about 5.8×10-5. The operation
time of users entering the system was significantly lower than that before system application, and the effective login rate was
significantly higher than that before system application, the difference was statistically significant (P<0.05). Conclusion Through
the upgrade of this project, it meets the needs of the hospital’s business growth and stable system operation within five years. And
it changes the inconvenience caused by the original entity USB_KEY login, allows medical personnel to easily log in to the system
through 1 second code scanning on their mobile phones, helps the hospital promote the development of paperless medical documents
business, prepares for the next step of the hospital’s CA business mobile phone upgrade, and provides a construction foundation for
medical data sharing in our hospital.
