摘要: 本文分析了目前煤矿安全生产远程综合监控系统在数据传输过程中存在的问题,提出了一种基于Zigzag置换的数据传输方法。这种传输方法的实质是数据在传输过程中采用若干次置换,每次置换可以采用不同或相同的方式,通过对数据进行多次置换得到加密文件。文章分析了算法的时间复杂度,试验表明该方法具有时间复杂度低,算法简单等特点。该方法可以有效的解决煤矿安全生产远程综合监控系统中对生产数据传输的安全性和实时性要求。

Abstract: This paper analyzes some problems that exists in the data transmission of long-distance synthesis monitors system in mine safety production at present, and proposes a new method based on Zigzag permutation. The substance of this permutation method is that every order of permutation can adopt methods with dissimilarity or sameness in data transmission. The secret-code files can be acquired by several data iterated. It has analyzed time complexity of this algorithm. The analysis indicates that the time complexity of the proposed method is 0(n2). The result indicates that the proposed algorithm can get satisfying effect in integrated monitoring system for mine safety production.
