Abstract:
An object is to provide a key generation method capable of maintaining a high security level in each of sliced networks when network slicing is applied to a core network. A key generation method according to this disclosure specifies network slice identification information indicating a network slice system that provides a service to be used by a communication terminal ( 50 ) among a plurality of network slice systems included in a core network ( 10 ) and, using the network slice identification information, generates a service key to be used for security processing in the network slice system indicated by the network slice identification information.

Claim (Index 6):
The key derivation method according to  claim 3 , wherein a key for integrity assurance processing and a key for encryption processing are derived from the common key.
