| 摘 要： | 为解决电子文档签名的真实性问题，提出了基于数字印章的解决方案．签发文档时用椭圆数字签名算法生成签名，签名作为水印嵌入到数字印章中；接收文档时，用水印算法提取数字印章签名，再用椭圆曲线数字签名算法验证签名．此方案具有安全性高、兼容性强、简单直观、方便使用等优点．

| Abstract: | A solution based on digital seal is presented to check the reality of the eletronic document signature. When a document is delivered, the signature of the document produced by the elliptic curve digital signature algorithm is embeded in the digital seal as a watermark, and when the document is received, the signature is abstracted by the watermark algorithm and is checked by the elliptic curve digital signature algorithm. The method has the advantages of good visuatization, high security and easy usage. |
