Due to the relatively large demand for hospital case information retrieval and the high probability of concurrent requests, the information security is greatly threatened. Therefore, the design of hospital case information retrieval system based on improved AES algorithm is proposed. Take the ARK-1123h processor and ADK3390-DH21 power supply device that can meet the multi task Internet information processing as the hardware of the system. After normalizing the case information by using the linear function conversion, the gradient parameters are integrated into the AES algorithm to encrypt the information, and the corresponding information is displayed in combination with the user identity authentication results. The test results show that the designed system can effectively ensure the security of hospital case information under the condition of concurrent access.
