Abstract
A security establishment method includes generating a pair of keys via mutual authentication between a terminal device (110) and a serving network, and the terminal device (110) and the serving network sharing KASME by using the generated pair of keys (Steps S50 and S100), the terminal device (110) and a roaming destination network of the terminal device (110) generating, by using the KASME, KSEAF mapped with SEAF (50) (Steps S140 and S150), and the terminal device (110) and the roaming destination network generating, by using at least the KSEAF and SUPI used to recognize a subscriber in the serving network, KAMF mapped with AMF (60) (Steps S140 and S150).
