摘要
近年来,随着Android平台在移动设备上的普及以及企业移动办公快速发展的趋势,Android平台上隐私文档的保护显得越发重要。基于已有文档保护方案的研究,提出一套可供普通应用程序使用的轻量级的移动终端文档保护方案。该方案使用多重密钥技术并结合密钥拆分算法,在保证文档安全性的同时,实现了对用户透明的文档加解密。该方案还可对受保护文档进行实时监控,以保证其在整个生命周期内的安全性。基于该方案在Android平台上实现了一个原型系统,并在多个Android手机平台上进行了测试,实验结果验证了该方案的可行性和兼容性。
As mobile devices of Android are becoming more and more prevalent among enterprises as well as the individuals,the protection of private documents on Android platform is getting more and more important. On the basis of existing researches,a lightweight mobile document protection scheme for general applications is proposed,which used the technology of key splitting and multiple-key system. The process of encryption and decryption is transparent to the user without any perceptible delay. The scheme provided real-time monitoring to protect the confidentiality of documents during the whole lifecycle. Moreover,a prototype system on Android platform has been implemented based on the scheme,and it had been tested on several Android platforms. Experiment results show that the scheme is practical and compatible with the mainstream Android platforms.
