Abstract
A method for providing a key derivation function (KDF) negotiation in a 5G network is provided. The method which includes: selecting a specific KDF at a UE and at the network for at least one security related key derivation; and transmitting, said selected KDF to the UE and to other network functions to indicate said selected KDF for generating specific security key at a receiver side.
Claims9
A target eNB connected to a target Access and Mobility Management Function (AMF) node, the target eNb comprising:
- one or more memories storing instructions;
- and
- one or more processors configured to process the instructions to control the target eNB to:
- at N2 handover, using an N2 reference point, from a source eNB connected to a source AMF node to the target eNB node, receive, from the target AMF node, a handover request message including security capability information of a User Equipment (UE);
- select information using the security capability information of the UE;
- and
- send a handover request acknowledge message to the target AMF node so that the selected information is sent to the UE.
A communication method of a target eNB connected to a target Access and Mobility Management Function (AMF) node, the communication method comprising:
- at N2 handover, using an N2 reference point, from a source eNB connected to a source AMF node to the target eNB, receiving, from the target AMF node, a handover request message including security capability information of a User Equipment (UE);
- selecting information using the security capability information of the UE;
- and
- sending a handover request acknowledge message to the target AMF node so that the selected information is sent to the UE.
A non-transitory computer-readable recording medium embodying a program, which when executed, causes a target eNB connected to a target Access and Mobility Management Function (AMF) node to perform a method comprising:
- at N2 handover, using an N2 reference point, from a source eNB connected to a target AMF node to the target eNB node, receiving, from the target AMF node, a handover request message including security capability information of a User Equipment (UE);
- selecting information using the security capability information of the UE;
- and
- sending a handover request acknowledge message to the target AMF node so that the selected information is sent to the UE.
