基于移动设备加密系统的设计与实现

为保障信息安全,政府部门和企业都建立了信息安全系统,对重要电子文档加密。然而,员工外出办公时,无法随时随地都携带着自己的电脑,有时必须使用他人或公共的电脑进行办公,在这种情况下无法保证机密文件的安全。文中提出了一种移动设备加密系统,将加解密功能固化到移动设备上,并由认证模式对本身的功能进行保护。密文文件可存储在移动设备上带出或通过互联网传输,而不用担心泄密风险。当到异地时,任何一台电脑都可以通过与移动设备的连接而进行对密文文件的使用,以此来保障信息的安全。

Design and Implementation of Encryption System based on Mobile Device

In order to ensure the information security, the government departments and the enterprises establish their information security systems and encrypt their important electronic documents. However, the computer could not be taken everywhere and anytime when the personnel and workers are out on business, and thus they have to use other or public computer in office work, this might bring threats to the information security. This paper proposes an encryption system based on mobile device. In this system, the encryption/decryption functions are installed on the mobile device, the system, with authentication mode, protects its own functions. Ciphertext files might be stored in the mobile device or transmitted through the Internet, so there is no worry about the risk of information leakage. When the personnel and workers are out on business, the ciphertext files on any computer could be used by connecting the mobile device, thus to ensure the information security.
