NETWORK KEY PROCESSING METHOD AND SYSTEM AND RELATED DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17819188 titled 'NETWORK KEY PROCESSING METHOD AND SYSTEM AND RELATED DEVICE

Simplified Explanation

The abstract describes a network key processing system that includes user equipment, a security anchor network element, and an access and mobility management network element. The system allows for the generation and distribution of slice-dedicated keys for network slices.

  • The security anchor network element obtains a first key parameter from a slice selection network element.
  • The first key parameter includes identifier information of N network slices.
  • The security anchor network element generates N slice-dedicated keys based on the first key parameter.
  • The security anchor network element sends the N slice-dedicated keys to the corresponding N network slices.
  • The access and mobility management network element obtains the first key parameter and sends it to the user equipment.
  • The user equipment generates the N slice-dedicated keys for the N network slices based on the first key parameter.
  • The user equipment can then access the N network slices using the generated N slice-dedicated keys.

Potential Applications

  • This technology can be applied in network slicing environments where different network slices require dedicated keys for secure communication.
  • It can be used in 5G networks to enable efficient and secure access to multiple network slices.

Problems Solved

  • Simplifies the process of generating and distributing slice-dedicated keys for network slices.
  • Enables secure access to multiple network slices without the need for separate authentication processes.

Benefits

  • Streamlines the key processing system in network slicing environments.
  • Enhances security by providing dedicated keys for each network slice.
  • Improves efficiency by allowing user equipment to access multiple network slices using the generated keys.


Original Abstract Submitted

Embodiments of this application disclose a network key processing system, including user equipment, a security anchor network element, and an access and mobility management network element, where the security anchor network element is configured to: obtain a first key parameter from a slice selection network element, where the first key parameter includes identifier information of N network slices; generate N slice-dedicated keys based on the first key parameter; and send the N slice-dedicated keys to the corresponding N network slices respectively; the access and mobility management network element is configured to: obtain the first key parameter, and send the first key parameter to the user equipment; and the user equipment is configured to: generate the N slice-dedicated keys for the N network slices based on the first key parameter, and access the N network slices based on the generated N slice-dedicated keys.
