    摘要:

    数字时间戳可以为电子文件提供准确的时间,并可以检验出文件在加上时间戳后是否被更改过。基于数字时间戳的线性链接机制、树型机制的优缺点,提出了混合模式,即整体结构使用树型机制,内部结构使用链接机制,该模式不需要安全信任TSA,并且验证时间也不会过长。针对电子病历存在的安全性问题,利用混合模式分别由病人和医生对病历和诊断加盖时间戳,使病历和诊断都具有一定的可靠性和匿名性。

    Abstract:

    Time-stamp can provide accurate time for electronic files and test if the file added time-stamp has been modified. Based on the advantages and disadvantages of the Linear-Linking Scheme and Tree-Like Scheme, a hybrid model is introduced, which creates the integral structure in Tree-Like Scheme and the internal structure in Linear-Linking Scheme needs no complete trust to TSA and the very long verifying time. Patients seal time-stamp on their medical records and doctors on their diagnosis based on the hybrid model to solve the secure problems of electronic medical records. Both patients’ medical records and doctors’ diagnosis have anonymity and reliability to a certain degree.
