【摘要】 Android系统作为开源的系统,受到越来越多的青睐,同时其安全性及用户的隐私也受到了极大的考验。本文提出了一种针对短信隐私保护的加密方案。从Android系统的整体架构及分层思想出发,通过对3DES对称加密算法及RSA非对称加密算法的原理进行分析与研究,提出了一种新型的针对Android系统的混合加密算法的短信加密方案,详细地介绍了具体的实现过程。使用Android模拟器进行的收发仿真实验,证明了短信加密方案的可行性。更多还原

【Abstract】 Android System, as an open source system, is more and more popular.At the same time, its security and user privacy face a great challenge.This paper puts forward an encryption scheme to protect the privacy of short message. Starting from the overall architecture and hierarchical idea of Android system, a new encryption scheme based on the hybrid encryption algorithm is proposed in this paper through the analysis and research on the 3DES symmetric encryption algorithm and RSA non symmetric encryption algorithm. The process of realizing algorithmis introduced in detail. The test by using the Android simulator to send and receive the short message proves the feasibility of the short message encryption scheme.更多还原
