在临床数据交换的过程中，图像数据的通信成为交换中越来越重要的部分，在传输的过程中，数据可能被截获、修改或公开。因此，许多用以保护这些图像的方法被提出来，防止其受到未授权的访问或者篡改；然而，它们均有一定的局限性。提出了一个结合RSA、AES和MurmurHash的加密框架，用来弥补这些局限性。在这个框架中，图像像素信息和剩余部分分别用AES和RSA加密，而图像的MurmurHash值也被嵌入到加密文件中以保证图像的完整性，从而提高整体的安全性和处理速度。通过正确的密钥，图像可以被恢复并且不损失信息。整个研究和测试在C#编译平台下完成。

Image data communication is playing a more and more important role in the process of clinical data exchange during which the data can be intercepted and revealed. Hence lots of methods have been proposed to protect the images from unauthorized access and alteration. Yet, they all have various limitations. This work proposes an encryption framework with RSA, AES and MurmurHash to ameliorate these issues. In which, pixels and the remaining are encrypted with AES and RSA separately, and MurmurHash is embedded to ensure image integrity, thereby improving the overall security and process performance. The images can be restored without any loss of information using the correct key. The whole experiment has been done in c#.
