阐明了数据采集的概念,分析了矿山数据采集系统中数据来源、数据特点,提出了矿山数据采集的系统分析与设计。探讨了经典的数据加密标准(Data Encyption Sslatlauid,DES)DES和RAS加密算法的优缺点,给出了基于DES和RAS的综合加密算法,并将该算法应用于虚拟专用网(VPN)安全框架中,确保了在数据采集网络安全性需求的同时满足了实时性需求。
The concept of data acquisition is expounded, the source and characteristics of data in the data mining system are analyzed, and the system analysis and design of mine data acquisition is proposed. The advantages and disadvantages of the classic Data Encyption Sslalauid (DES) DES and RAS encryption algorithms are discussed. The integrated encryption algorithm based on DES and RAS is given. The algorithm is applied in the virtual private network (VPN) security framework , To ensure that the data acquisition network security needs at the same time meet the real-time needs.
