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.

Abstract: Embodiments of the present disclosure provide a network access authentication processing method and device. 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: A a method for maintaining a Point-to-Point Protocol (PPP) session when a terminal is powered off is provided. The method includes that a network side receives terminal power-off indication information sent by a terminal when the terminal is powered off (101); and when determining according to the terminal power-off indication information that the terminal needs to maintain a PPP session in a power-off state, a PPP session release operation is not triggered (102). A system, a network side, a terminal and a computer storage medium for maintaining a PPP session when the terminal is powered off are also provided.
