DICOM医学图像文件数字签名的实现

摘要

目的:对DICOM医学图像进行数字签名.保证其信息的完整性、不可抵赖性、真实性和可靠性.方法:利用OpenSSL工具包及DCMTK工具包中的dcmsign对DICOM医学图像中的相关信息进行签名,并保存在同一DICOM文件的后面.结果:经签名后的DICOM文件可鉴定文件中信息的完整性、不可抵赖性、真实性和可靠性.结论:利用OpenSSL工具包及DCMTK工具包中的dcmsign对DICOM文件数字签名可实现其在远程医疗及区域PACS传输中的安全性.%Objective: To ensure the integrity、non-repudiation、authenticity of pictures and relevent messages by making a digital signature for a DICOM file. Methods: By using OpenSSL toolkits and dcmsign of DCMTK toolkits, make a digital sig nature for the relevent messages of DICOM medical image and then save it behind of the DICOM file. Results: We can evaluate integrity、non-repudiation、authenticity of pictures and relevent messages in the DICOM file which has been made a digital signature. Conclusion: To make a digital signature in a DICOM file by using the OpenSSL toolkits and dcmsign of DCMTK toolkits can realize the security when DICOM file transported in remote medical treatment and PACS.
