移动应用中ICE算法的设计与实现

Design and Implementation of ICE Algorithm in Mobile Application

移动通讯技术的快速发展使移动下载服务越来越普及。针对手机存储容量有限和文件版权保护的问题,提出一种针对二进制文本文件的ICE算法,它基于著名的压缩算法Huffman,通过在压缩过程加入密钥实现文件压缩和加密的一次运算完成,不仅节约了手机存储空间,而且避免了文件的恶意传播。通过仿真实现,ICE算法在加密强度、压缩效率、内存占用、运行时间、代码大小上具有良好效果,证明了ICE算法在移动文件下载服务的有效可行性。

Mobile downloading service is becoming more and more popular with the rapid development of mobile communication technology. Faced with the two problems about the limited storage space in mobile phone and file copyright protection, a new algorithm named ICE（Integration Compression and Encryption）algorithm is designed aimed at the bi- nary text file based on a famous compression algorithm-Huffman, to simultaneously realize both file compression and en- cryption in one computing by adding key in the compression process, not only to save mobile phone storage space but to avoid file malice transmission. Through emulated experimentation, the result shows ICE algorithm has some desired ef- fect in encryption intensity, compression efficiency, committed memory, operation time and the size of code, proving the algorithm, is to some extent, effective and feasible in mobile file downloading service.
