    Abstract: A security capability negotiation method is provided that is applicable to perform security capability negotiation during a mobile network handover. Moreover, a security capability negotiation system is also provided. Consistent with the provided system and method, it may be unnecessary for the MME to know the security capability of the corresponding eNB in a certain manner during a handover from a 2G/3G network to an LTE network. Meanwhile, during the handover from the LTE network to the 3G network, the SGSN does not need to introduce new requirements.

    Abstract: A method for negotiating security capabilities during movement of a User Equipment (UE) includes the following steps: a target network entity receives a Routing Area Update (RAU) Request from the UE; the entity obtains Authentication Vector (AV)-related keys deduced according to a root key, and sends the selected security algorithm to the UE; and the UE deduces the AV-related keys according to the root key of the UE. A system, SGSN, and MME for negotiating security capabilities during movement of a UE are also disclosed. The present invention is applicable to security capability negotiation between the UE and the network.

    Abstract: A method and an apparatus for performing verification using a shared key are disclosed. The method includes: receiving, by a first network element, a registration request message from a second network element, where the registration request message includes a user identifier, first network identifier information, and second network identifier information, the second network identifier information is obtained by processing the first network identifier information by using a shared key, and the shared key is a key used between the first network element and the second network element; verifying, by the first network element, the registration request message by using the shared key; and sending, by the first network element, a registration response message to the second network element. When receiving a registration request from a visited network, a home network verifies the registration request message by using a shared key, to avoid a spoofing attack from the visited network.

    Abstract: The present invention relates to a method, an apparatus, and a system for protecting cloud data security. A key management center encrypts original data M sent by a first terminal using a key K, and uploads encrypted data C1 to a cloud server. When the key management center receives a request from a second terminal for the data M, it generates encrypted data C2, which is generated by first encrypting C1 with a key Kb of the second terminal and then decrypted by the key K that was used to encrypt the original data M to generate C1. The key management center then sends the encrypted data C2 to the second terminal. The second terminal decrypts the encrypted data C2 using its own key Kb to obtain the original data M.

    Abstract: Embodiments of this application relate to a service authorization method and system, and an apparatus. The method includes: A first NRF receives a first request requesting an access token for accessing service of a second NF in a second network from a first NF, where the first NF and the first NRF are located in a first network, and the first request includes SNPN information of the first network and/or the second network. The first NRF forwards the first request to a second NRF located in the second network. The second NRF generates an access token in response to the first request, where the access token includes the SNPN information of the first network and/or the second network. The second NRF sends the access token to the first NRF. The first NRF receives the access token and sends the access token to the first NF.

    Abstract: A signaling attack prevention method and apparatus is provided. The signaling attack prevention method can include receiving a Diameter request message sent by a mobility management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN); and determining whether the Diameter request message is received through a roaming interface. When the Diameter request message is received from the roaming interface, the signaling attack prevention method can include determining whether a characteristic parameter of the Diameter request message is valid; and if the characteristic parameter of the Diameter request message is invalid, the method can include discarding Diameter request message or returning, to the MME or the SGSN, a Diameter response message carrying an error code. In this way, a hacker can be effectively prevented from attacking an HSS or an edge node by using each attack path, and communication security is improved.
