办公系统中可验证的数字签名方案研究

数字签名技术保证了签名内容的不可更改性和来源的真实性。用户可以利用动态数字签名认证实现可靠的身份确认功效。本文针对分布式层次化网络安全应用,提出了一种分布式简化严格层次结构的PKI信任模型,为网络应用提供有效的认证、访问控制、授权、机密性、完整性、非否认性服务。在该信任机制体系模型基础上,提出并建立了由CA签发的签名证书的概念,来保证CA所辖域中签名文件的安全。

Research on Validated Digital Signature Scheme in OA System

The user can make use of the dynamic digital signature attestation which can achieve the reliable identity affirm efficacy,compare to the traditional code,It enhances the security of communication system at maximum,and it is used more convenient and easy.To solve the distributed hierarchical network security problems,a distributed simple strictly hierarchical(DSSH)PKI trust model is presented.This model provides effective network security services such as authentication,access control,integrity,confidentiality,non-repudiation and so on.On the basis of the trust model,the concept of the issue-seal certification is presented and established to ensure the security of the seal file in the CA domain.
