Abstract: A weeding device for crops having a seedling avoidance function includes a rack connected to a weeding machine. A hydraulic pump and two hydraulic cylinders are mounted to the rack. Bottom ends of each of the two hydraulic cylinders are provided with a vertically arranged support rod. An inter-row weeder is mounted to a bottom end of each of the two support rods. A slider configured to reciprocate in a horizontal direction is positioned on two slide rails that are mounted to the rack. An inter-plant weeder is mounted to a bottom side of the slider. A plurality of weeder blades are arranged side by side on the inter-plant weeder. At the weeding position, an arrangement direction of weeder blades is perpendicular to an advancing direction, and at the weed avoidance position, the arrangement direction of the weeder blades is parallel to the advancing direction, thereby avoiding crops.

The method includes: receiving a confirmation message sent by user equipment, the confirmation message carrying a first signature token generated by the user equipment according to a first Privacy enhanced Mobile Subscriber Identifier (PMSI); verifying whether the first signature token is valid; and when the first signature token is invalid, obtaining the PMSI to perform network access authentication on the user equipment.

Abstract: Provided are a key derivation method and device. The method includes: acquiring a slice identifier corresponding to a network slice to which a user equipment is currently attached, where the slice identifier uniquely identifies the network slice; and transmitting the slice identifier to a designated communication device. The slice identifier is configured to instruct the designated communication device to derive, according to the slice identifier, an intermediate key required by the network slice. By means of the technical solution described above, the problem in the related art that a slice function cannot be implemented normally due to the fact that different network slices probably use the same intermediate key may be solved, and different network slices may correspond to different intermediate keys, thereby avoiding a case that the slicing function cannot be implemented normally caused by allocating the same intermediate key to different network slices.
