Abstract:

With the accelerated deployment of 5G new infrastructure, terminal application business has been gradually extended to various vertical industries.Although 5G technology can also adapt to the differentiated communication requirement for power industry, the power industry currently lacks a kind of 5G module that not only meets the security access requirement for power grid, but also has the advantage of low hardware upgrade cost, flexibility and scalability.Therefore, a 5G lightweight hardware encryption module for power terminals was designed and developed.The module is connected with the power terminal in the form of pluggable interface, and the capability of 5G communication and encryption authentication could be quickly realized just by terminal software upgrade.The test results show that the module has chip-level security authentication capability, and can take into account 5G communication and security mechanism, which not only improves the security of terminal access to the power intranet, but also reduces the difficulty of terminal transformation and 5G communication hardware upgrade cost.

Key words: 5G module, power terminal, secure access, hardware encryption, lightweight
