摘 要:企业关键数据向移动终端设备延伸,使移动终端数据泄露成为企业面临的一个新的问题。针对移动终端
数据泄露问题,提出了基于预解密的透明加密技术,有效解决移动终端传统透明加密技术只能保证应用层安全的
缺陷,并提升了透明加密性能。同时,利用瘦客户端与移动终端数据防泄露相融合的思想,进一步设计面向移动
终端的虚拟远程桌面技术,彻底屏蔽数据流传输的弊端,保证了移动终端数据的安全传输。在此基础上,设计与
实现了一套面向移动智能终端的数据防泄露系统。

Abstract: With the trend that enterprise key data moves to mobile terminal, data leakage prevention has become an im-
portant issue on mobile terminal. To solve the problem, a pre-decryption transparent encryption technology was set up which
solved the problem that traditional transparent encryption technology only can ensure application layer security, in addition,
performance on mobile was improved. At the same time, taking advantage of the idea of combining thin client and mobile
terminal to prevent leakage of data, a virtual remote desktop technology on mobile was proposed, which completely shield
the shortcomings of data transmission and ensure the safe transmission of mobile terminal data. Finally, a data leakage pre-
vention system for mobile terminal was set up, which makes the mobile terminal fully and effectively protected.
Key words: data leakage prevention, transparent encryption, virtual remote desktop
