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.
