    摘要: A method for preventing abuse of an Authentication Vector (AV) and a system and apparatus for implementing the method are provided. Access network information of a non-3rd Generation Partnership Project (3GPP) access network where a user resides is bound to an AV of the user, so that when the user accesses an Evolved Packet System (EPS) through the non-3GPP access network, even if an entity in the non-3GPP access network is breached, or an Evolved Packet Data Gateway (ePDG) connected to an untrusted non-3GPP access network is breached, the stolen AV cannot be applied to other non-3GPP access networks by an attacker.

    摘要: An innovative routing method for an integrated circuit design layout. The layout can include design netlists and library cells. A multiple-level global routing can generate topological wire for each net. An area oriented graph-based detail routing on the design can be performed. A post route optimization after the detail routing can be performed to further improve the routing quality. Some methods can be single threaded all or some of the time, and/or multi-threaded some or all of the time.

    摘要: Embodiments of the present invention disclose a method, an apparatus, and a system for data transmission. The method for data transmission includes: determining that data to be transmitted is control plane signaling related to a user equipment that camps on a relay node; and transmitting the data through a first user data bearer established between the relay node and a donor base station, where the first user data bearer provides integrity protection for the data. According to the embodiments of the present invention, when the control plane signaling related to the user equipment that camps on the relay node is transmitted between the relay node and the donor base station, integrity protection is provided for the control plane signaling, and therefore attacks such as the denial of a service attack are prevented.

    摘要: Method, device, and system for deriving keys are provided in the field of mobile communications technologies. The method for deriving keys may be used, for example, in a handover process of a User Equipment (UE) from an Evolved Universal Terrestrial Radio Access Network (EUTRAN) to a Universal Terrestrial Radio Access Network (UTRAN). If a failure occurred in a first handover, the method ensures that the key derived by a source Mobility Management Entity (MME) for a second handover process of the UE is different from the key derived for the first handover process of the UE. This is done by changing input parameters used in the key derivation, so as to prevent the situation in the prior art that once the key used on one Radio Network Controller (RNC) is obtained, the keys on other RNCs can be derived accordingly, thereby enhancing the network security.

    摘要: Integrated high efficiency lateral field effect rectifier and HEMT devices of GaN or analogous semiconductor material, methods for manufacturing thereof, and systems which include such integrated devices. The lateral field effect rectifier has an anode containing a shorted ohmic contact and a Schottky contact, and a cathode containing an ohmic contact, while the HEMT preferably has a gate containing a Schottky contact. Two fluorine ion containing regions are formed directly underneath both Schottky contacts in the rectifier and in the HEMT, pinching off the (electron gas) channels in both structures at the hetero-interface between the epitaxial layers.
