Abstract: Embodiments of this application disclose an inductor device wiring architecture, including an inductor device and a plurality of dummy metals located under the inductor device. The plurality of dummy metals are arranged in a plurality of metal layers. Each of the plurality of metal layers corresponds to some of the plurality of dummy metals. Arrangement areas of dummy metals corresponding to at least two of the plurality of metal layers progressively increase in a direction away from the inductor device. In the inductor device wiring architecture, adverse effects on performance of the inductor device can be reduced, and a product yield can be increased. The embodiments of this application further disclose an integrated circuit and a communications device.

Abstract: This application discloses a method for Internet key exchange protocol (IKE) authentication using a certificate. The method includes: A first device parses a certificate to obtain signature information in the certificate. The first device fills an AUTH payload field in an IKE identity authentication (AUTH) message based on the signature information in the certificate, where signature information indicated by the AUTH payload field matches the signature information in the certificate. The first device sends the IKE AUTH message to a second device. In the method for Internet key exchange protocol IKE authentication using a certificate provided in this application, the first device may automatically parse the signature information in the certificate, and fill the related field of the IKE AUTH message based on the signature information. Therefore, user configuration is simplified and product usability is improved.
