AI Technical Summary
Technical Problem
In existing technologies, the exchange of electronic medical records involves multiple information interactions, resulting in high consumption of network bandwidth resources and a lower threshold for malicious attacks.
Method used
Electronic medical record exchange is achieved using an elliptic curve-based commitment formula (Pedersen commitment). Information verification and key exchange are completed in a single commitment transmission, reducing network bandwidth consumption.
Benefits of technology
It enables information verification and key exchange to be completed in a single information exchange, reducing network bandwidth resource consumption and improving transmission security.

Abstract
本发明公开了一种电子病历共享方法、装置、电子设备及可读存储介质，包括：接收对端设备发送的电子病历传输请求，从电子病历传输请求中解析得到第一承诺值；判断第一承诺值是否满足基于椭圆曲线的承诺公式；若是，则遍历当前存储的电子病历承诺值集合，判断电子病历承诺值集合中是否存在与第一承诺值对应的第二承诺值，若是，则将第二承诺值以及第二承诺值对应的电子病历发送至对端设备；其中，采用基于椭圆曲线的承诺公式根据己方私钥生成电子病历承诺值集合。本方法采用基于椭圆曲线的承诺公式(基于EC曲线的Pedersen承诺)实现电子的病历交换，仅需一次承诺的传输即可同时完成信息验证与电子病历的，有效缩小网络带宽的消耗。
