为解决传统电子政务身份认证模型所存在的诸如可实施性差、验证结果缺乏证明、低可信度等问题,设计一种开放式的电子政务身份认证模型,该模型中CA(Certificate Authority)中心独立进行2个验证服务,把传统的OCSP(Online Certificate Status Protocol)应答机制更改成提供身份证明文件的方式,能够较好地解决上述缺陷。利用云信任评估模型,量化评估这2种认证模型,验证提出的开放式身份认证模型的信任度有了较大提升。此外,对该模型进行原型实现,重点优化了其性能,实验表明该模型具备较好的实用价值。
In order to solve the problems existing in traditional e-government identity authentication models, such as poor implementability, lack of verification results and low credibility, an open e-government identity authentication model is designed, in which CA (Certificate Authority) Carrying out two verification services and changing the traditional Online Certificate Status Protocol (OCSP) response mechanism to provide identity documents can better solve the above defects. By using the cloud trust evaluation model, the two kinds of authentication models are quantified and evaluated, and the trust of the proposed open authentication model has been greatly improved. In addition, the model is prototyped and its performance is optimized. Experiments show that the model has good practical value.
