摘要
提出了密钥分解问题的向量空间投影理论,由此给出了密钥分解算法,并且将该理论和算法引入文件分割问题的研究中,给出了一种应用于实际保密场合的文件安全分割及恢复算法,实现了将文件分割成n个子文件,而从其中任意m(1≤m≤n)个子文件恢复原文件的功能,为重要文件的存储和传输提供了安全保证.最后对在通信保密中实现信息的分解保密提出了建议.
The vector space projection theory for key decomposition is put forward.Based on this,a new key decomposition algorithm is presented.This theory and algorithm are used in the research of the safe division of files,and the algorithm for safely dividing file is obtained it can divide a file into sub-files,and then the original file can be restored from arbitrary m sub-files of n sub-files (1≤m≤n).This provides the safety guarantee for the memory and transmission of important files.Finally,some proposals about the information decomposition in security communication are presented.
