Research on Secure Access Technology of Electric Power Wireless Private Network Based on Hybrid Encryption

In recent years, as mobile access systems are gradually being used in smart grids, users can obtain grid resources anytime and anywhere using mobile terminals. In this paper, the data in the mobile device is sneaked and the sensitive information is leaked. The SSL VPN technology is used to construct the encryption channel. The comprehensive security protection model based on the layered architecture is proposed. By comparing the advantages and disadvantages of symmetric and asymmetric encryption algorithms, this paper adds A hybrid encryption algorithm that combines PKI technology to enhance the secure transmission of mobile data. Experiments show that the built model can effectively protect mobile devices and sensitive data, ensuring the security of intranet applications.
