To meet the current security requirements of 5G edge computing nodes, this paper proposes a bidirectional remote attestation method for 5G edge computing nodes. The method uses the vTPM technology to extend the trust chain of the physical TPM to the container which running on the operating system, and the MEC controller completes the trustworthiness verification of the container. At the same time, the UDM is used to verify the trustworthiness of the 5G end users. A remote attestation agent UPF is introduced between the end users and the 5G containers. The UPF coordinates bidirectional remote attestation to avoid the problem of leaking container and/or user data. We simulated our scheme, and the results show that this scheme can meet the security requirements of bidirectional remote attestation of electricity 5G nodes.
