随着中国电子政务与电子商务的发展,电子文档已经逐渐取代传统的纸质文档。因此,如何保证电子文档的安全已经成为电子政务与电子商务进一步深入与成功应用的关键。采用组合公钥密码体制（Combined Public Key,CPK）设计电子签章系统,利用ID证书来进行数字签名与验证,使任何两个用户之间仅通过对方身份标识即可确认公钥信息,不依靠可信第三方验证,并简化了密钥交换协议,保证了文档的完整性、机密性和不可抵赖性,实现了高效安全的电子签章系统。

With the development of e-government and e-commerce,the electronic documents have gradually replaced traditional paper-based documentation. Thus,how to ensure the security of the electronic document has become the key to the farther successful application of e-government and e-business.？The adoptions of CPK（Combined Public Key） in the design of electronic signature system and ID certificate in digital signature and verification,could make any two users confirm public key information only by their own identity labels with any dependence the trusted third party validation,thus simplifying the key exchange agreement,ensuring the documents integrity,confidentiality and undesirability,and realizing the efficient safe electronic signature system.
