Abstract:
The objective of the present invention is to provide a communication system with which it is possible to implement advanced security in a 5G communication system. A communication system according to the present disclosure is provided with: a communication terminal (10); an access and mobility management (AMF) entity (20) which executes a mobility management (MM) process relating to the communication terminal (10); and a session management function (SMF) entity (30) which executes a session management (SM) process relating to the communication terminal. The communication terminal (10) transmits an MM message, which is used in the MM process and to which a first security key has been applied, to the AMF entity (20), and transmits an SM message, which is used in the SM process and to which a second security key has been applied, to the SMF entity (30) via the AMF entity (20).
