This paper analyzes the disadvantages of the traditional method of data security between the master station and the terminal, and proposes a new method of data exchange between the master station and the terminal. This method improves the security of data interaction. In the process of using it, symmetric algorithm and asymmetric algorithm are combined, involving security mechanisms such as signature, certificate, MAC and symmetric encryption, so as to establish a secure link between the master station and the terminal, so as to protect the communication security between them. |
