传统的数据安全传输方法在写入数据时使用单线程方式,导致数传输速度较慢。为了提高数据传输效率,本文基于嵌入式技术设计了一种新的电力监控网络数据安全传输方法。首先,将数据代换由单线程变为多线程,使用字节代换与位移代换方式分组加密与解密电力监控网络数据;然后,基于嵌入式技术重组数据流、设定加密与解密系数,并校验电力监控网络数据的安全性与完整性;最后,在提取哈希函数值基础上,设计了电力监控网络数据安全传输算法。测试结果表明,嵌入式技术在数据加密、数据传输以及数据解密中用时均少于传统方法,可见本文方法在传输数据时用时最短、效率最高。

Traditional data security transmission methods use single thread to write data,resulting in slow data transmission speed.In order to improve the efficiency of data transmission,a new method of data security transmission in power monitoring network based on embedded technology is designed.The data substitution is changed from single thread to multi-thread,and the byte substitution and displacement substitution are used to encrypt and decrypt the power monitoring network data in groups.Then,based on embedded technology,the data stream is reconstructed,and the encryption and decryption coefficients are set to verify the security and integrity of power monitoring network data.Finally,based on the extraction of hashing function value,an algorithm for secure data transmission in power monitoring network is designed.The comparative test results show that the embedded technology takes less time in data encryption,data transmission and data decryption than the traditional method,which shows that the method in this paper takes the shortest time and has the highest efficiency in data transmission.
