铁卷运行原理
铁卷采用的原理是内核文件实时透明加解密，在操作系统底层对文件进行加解密操作，不影响人员的原有使用习惯。安装铁卷的用户在使用文件时，运行于驱动层的用户终端自动将文件实时加解密；文件的接收者必须经过管理中心端的认证，才能够根据许可权限对文件进行操作。,Rail volumes using Volume Rail operating principle of the principle of transparency are core documents in real-time encryption and decryption, the operating system at the bottom of the document encryption and decryption operations, does not affect the previous usage. Rail users to install volume in the use of documents, running on the driver layer of user terminals in real-time automatic file encryption and decryption　document management center to be the recipient-side authentication, only be able to document permissions under license to operate.
