  • Patent number: 10674416
    Abstract: Embodiments provide a user equipment (UE) device that includes a processor and a transceiver. The processor is configured to direct a handover request to an evolved packet core (EPC) access node via the transceiver. The access node may be, e.g. a wireless local area network (WLAN) access point or an E-UTRAN access point. The handover request may initiate a transfer of connectivity of the UE device from the WLAN access point to the E-UTRAN access point, or from the E-UTRAN access point to the WLAN access point. The processor is configured to receive a handover response from the current access node, wherein the response includes a cryptographic key identifier, and to derive a handover key from the key identifier. The processor may then operate the UE device to provide connectivity based on the handover key between the UE device and the other of the access nodes.

  • Patent number: 10673872
    Abstract: A threat level is evaluated for an ongoing attack detected for a set of resources based on received notifications having low weight in the evaluation of the threat level. If the threat level is smaller than an entrapment threshold, sensors associated with resources of an information system infrastructure that are potential subsequent targets of the ongoing attack are activated, the weight of the notifications sent from the activated sensors are set as average weight in the evaluation of the threat level, and the threat level is further evaluated for the ongoing attack. If the threat level is greater than the entrapment threshold, traps are deployed in the information system infrastructure, the weight of the notifications sent from the deployed traps are set as high weight in the evaluation of the threat level, and the threat level is further evaluated for the ongoing attack.

  • Patent number: 10645064
    Abstract: Improved virtualized application performance is provided through disabling of unnecessary functions, such as unnecessary encryption and decryption operations. An example method performed by a hypervisor includes the steps of obtaining a request to one or more of encrypt and decrypt a communication between a first virtual machine and a second virtual machine; determining if the first and second virtual machines execute on a same host as the hypervisor (e.g., by evaluating a context of the communication); and processing the communication without encrypting or decrypting the communication if the first and second virtual machines execute on the same host. Lawful Interception is performed by forwarding an unencrypted version of the communication to an authorized agency.
