1. A key processing method, comprising:
obtaining, by a security anchor network element, a first key parameter, wherein the first key parameter comprises identifier information of N network slices which are to be accessed by a user equipment;
generating, by the security anchor network element, N slice-dedicated keys based on the first key parameter;
sending, by the security anchor network element, the N slice-dedicated keys to the corresponding N network slices respectively; and
sending, by the security anchor network element, the first key parameter to an access and mobility management network element, which further sends the first key parameter to the user equipment.
