Abstract: Edge computing effectively relieves the computing pressure of cloud platform and reduces the consumption of network transmission bandwidth, but it brings new security problems as well, the traditional authentication mechanism no longer applies to “cloud-edge-end” network architecture. We proposed a lightweight two-way authentication protocol based on cloud-edge collaboration. In view of the limited resources of massive power terminal, the protocol is only based on a Hash and XOR operation to achieve certification, so it reduces the pressure of terminal calculation and transmission bandwidth. Its security was successfully verified by AVISPA tool together with informal analysis. The analysis and simulation results show that the protocol can resist replay attack, impersonation attack and so on. In addition, the comparison with similar protocols shows that the protocol has less computation and communication overhead.

Key words: edge computing, electrical terminal, mutual authentication, lightweight
