Abstract

The present disclosure provides an encrypted transmission system and method for medical data, which relates to the technical field of medical data. A server, in response to a medical data analysis request, performs encrypted transmission of model parameters with each client by the following steps: the server receives a model parameter acquisition request sent by the client; the server performs identity authentication of the client based on request authentication information corresponding to the client; when the identity authentication of the client is passed, the server generates a key string based on historical optimized model parameters corresponding to the client and performs encryption on a current round of to-be sent optimized model parameters to generate a ciphertext data packet and send to the client; the client determines a decryption key based on the identifier and decrypts the received ciphertext data packet to obtain the optimized model parameters; and the client updates a local analysis model based on the obtained optimized model parameters, enabling the server to determine a next round of optimized model parameters for the client.
