A Matrix Based Operation Design of Data Segmentation Encryption Method for SG-eIoT Terminals

In this paper, an encryption method of SG-eIoT collection terminal information is designed, which encrypts the information segmentally and makes the encrypted form structure unchanged, to increase the security. Matrix multiplication is used as a mathematical model of the encryption process, to facilitate control and statistics of the encryption process on the overall architecture. Each element participating in the matrix multiplication comes from the segmented data form, and each data form is standardized from each data recorded in accordance with the IEEE 1451.2 standard. Therefore, the processing of the data is both in accordance with the standard specifications, and is realized in the re-combination, which has better operability and security.
