Dependent claims

A data transmission method applicable to a control plane function entity, comprising:

determining target user plane data which needs to be subjected to security protection between a target user equipment and a user plane function entity;
sending a notification message to a Radio Access Network function entity and the target user equipment;
and
receiving a first key generated by the target user equipment, and sending the first key to the user plane function entity,
wherein the notification message is configured to instruct that the security protection is performed on the target user plane data between the target user equipment and the user plane function entity, and
wherein the first key is configured to be directly used by the user plane function entity and the target user equipment to perform the security protection on the target user plane data between the target user equipment and the user plane function entity.

3 more elements

A data transmission method applicable to a user plane function entity, comprising:

receiving a first key sent by a control plane function entity, wherein the first key is configured to be directly used by the user plane function entity and a target user equipment to perform security protection on target user plane data between the target user equipment and the user plane function entity, the first key is generated by the target user equipment and is returned to the control plane function entity by the target user equipment;
and
performing the security protection on the target user plane data transmitted between the target user equipment and the user plane function entity with the first key.
