基于ECC的病历文档内容抽取签名方案的研究


  摘 要:针对当前电子病历交互信息的机密性、患者的隐私权及签名效率过低等问题,提出基于椭圆曲线密码体制(ECC)的内容抽取签名方案。该方案能从签名过XML病历文档中抽取指定部分,并能认证出抽取部分是由原始签名者签名,从而隐藏患者的隐私信息。实验结果表明,该方案整体实现效率较高,有较好的可操作性及可扩展性。

  Abstract:Interactive view of the current electronic medical recorded confidentiality of the information, the patient’s privacy and signature low efficiency problem and so on, this paper put forward the content extraction signature scheme based on elliptic curve cryptography. The scheme signed off from the XML medical record to extract the specified section and could be certified out of the extracted part was signed by the original signer in order to hide the patient’s private information. The experiment indicates that the scheme as a whole to achieve higher efficiency, better operability and scalability.
