摘要
基于Android平台的智能手机安全应用开发已经越来越引起人们的关注。为了提升智能手机短信加密的安全强度,本文基于IDEA加密算法设计了一套Android平台下智能手机短信加密解密的程序。文中首先对Android的系统构架及应用程序的组成进行了分析,介绍了Android系统应用开发的便捷性和应用层的安全机制。其次对采用IDEA算法的原因进行了研究。描述了手机短信加密系统的设计思路,通过Android SDK模拟器进行了加密短信收发以及加解密算法效率的仿真测试,结果表明手机短信能够实现加密和解密的安全高效率传输。
security application development, which is based on intelligent mobile phone of Android platform, has been paid more and more attention. In order to enhance security strength of encryption with intelligent mobile phone short message, an intelligent mobile phone short message encryption and decryption software under the Android platform is designed in this paper, which is based on IDEA en- cryption algorithm. Firste, Android＇ s system architecture and application composition are analyzed in this paper, which points out that Android system＇ s convenient application development and security mechanism of application layer. Secondly, the reason for using IDEA algorithm is studied. Thirelly, then, the design methods concerning encryption system is described in mobile phone short message.The sending and receiving as well as algorithm efficiency of encryption and decryption simulations test with Android SDK simulator indicate that mobile phone short message can realize safe and high efficient transmission with regard to encrypt and decrypt.
