摘　　要：在图书文档传递中采用基于身份的加密和数字签名,实现了对图书电子文档进行合法性和完整性校验,给出了基于公钥证书的数字签名技术,使其在数字图书馆成功应用.在图书电子文档传递过程中,采用基于身份的数字签名可以省去对公钥证书的管理和维护的代价,无需传递文档发送者的数字证书,电子文档接收者也无需验证公钥证书的合法性,从而节约了带宽,减少了计算量,大大方便了数字图书馆的用户.the validity and integrality of the document were verified using ID-based digital signature and en- cryption during the transmision of E-books and the digital documents, and the application of ID-based sig- nature scheme in digital library was proposed. The results showed that the cost of the management and maintain of certificates for public key users can be omitted duiring the transmission of E-books and the dig- ital documents. During sending a digital document, it does not to transmit the sender＇ s public key certifi- cate, and the receiver of the digital document does not to verify the validity of the public key certificate, so it saves the width and reduces many computation, which provides more convenience for the users of digital library.
