摘要： 为实现适用于所有应用程序所产生数据文件的加解密方案，提出基于可信进程读写的文档加解密系统。将文件加密属性以一定长度的信息块写入文件尾部，构成文件的加解密识别标志。采用固定算法的安全套接层通信机制，确保在客户/服务器模式下可信通道建立时的高效性和数据传递的安全性。

Abstract: To encrypt and decrypt the data generated by all types of application software, this paper proposes a document encryption and decryption system based on the trusted process reading and writing, in which a information block with certain length wrote to the tail of file is used to identify the file encryption attribute. In order to ensure the efficiency of establishing the credit path and the security of data communication between the client and server, the fixed algorithm for SSL communication mechanism is used.
