摘要
针对电子文档的溯源防伪需求,提出一套完整的电子签章系统方案。借用PKI/CA技术体系实现对签章人身份的认证,采用目前安全性最高的椭圆曲线电子签名算法(ECDSA),综合利用单向散列函数和数字水印技术,实现印章管理、签章及验章等基本功能,通过ActiveX控件与Word文档集成实现整个电子签章系统的研发。实验结果和对比分析结果表明,该电子签章方案安全性高、处理速度快,具有较强的实际应用价值。
For the traceability security requirements of electronic documents,electronic signature system solution was proposed.The PKI/CA technology system was used to realize the authentication of the identity of the signer,and the elliptic curve electronic signature algorithm(ECDSA)with the highest security was adopted.One way hash function and digital watermarking were used to realize the basic functions of seal management,signature and examination.The whole electronic signature system was developed through the integration of ActiveX controls and Word documents.Experimental results and comparative analysis show that the electronic signature scheme proposed has high security and processing speed,and it has strong practical application value.
