摘　　要：在传统基于公钥基础设施的数字签名技术中,签名文件的传输通常会受制于用户双方之间的环境、终端以及文件格式等因素,且不同签名系统之间所签名的文件不能兼容。为此,分析并研究云端数字签名技术及其所具备的优势、具体签名协议和签名流程。在此基础上,设计云端数字签名系统,将该系统应用架设在云端服务器上,用户只需与云端服务器进行简单的文本交互,即可实现签名文件的跨平台操作。应用结果表明,该云端数字签名系统的签名操作具备统一性、便捷性、广泛性等特点,同时能保证所签文件相互兼容,并且安全性高、设备维护成本低。Transmission signed file transfer of digital signature technology based on Public Key Infrastructure（PKI） 1s usually subject to factors such as the environment,the terminal,and the file format between the users, and the signatures between different signature systems are not compatible either. In order to solve these problems, this paper analyzes and studies the cloud digital signature technology, including its advantages, specific protocol and signature procedure, and designs the cloud signature system. The system applications are put on the cloud server, and users only need a simple text interaction with the cloud server to achieve cross-platform operation of signature files. The application results show that the signature operation of the cloud digital signature system possesses the features of unity, convenience and universality. The system can ensure that the signed files are compatible with each other and have the characteristics of high security and low cost of equipment maintenance.
