  • PLC SYSTEM
    Publication number: 20170111048
    Abstract: In some embodiments, a PLC system includes a memory unit configured to back up user data stored in a MCU thereto when the power supply from the power module is interrupted, a capacitor configured to be charged by the power module and supply accumulated power to the memory unit when the power from the power module to the MCU is interrupted, a variable resistor unit configured to be coupled between the power module and the capacitor, and a switching unit configured to alternatively couple either the power module or the capacitor to the memory unit depending on a state of power being supplied from the power module. Some embodiments may provide advantages that a PLC system can supply much more power while reducing a charging period of time of an auxiliary power supply for supplying power with urgency when an abnormality occurs in a power module of the PLC system.

  • KEY HIERARCHY FOR NETWORK SLICING
    Publication number: 20170111339
    Abstract: A method is provided for facilitating service-specific security while avoiding a full authentication and key agreement exchange each time a service is activated on a device. Multiple services on a single device and sharing the same session link (e.g., radio link or radio bearer) and the same physical network may nonetheless obtain distinct service-specific network connectivity root keys from which service-specific security/session keys may be derived. In such case, instead of performing a full authentication and key agreement exchange with an operator or provider (e.g., home subscription server or HSS), the device may authenticate a network slice using a security credential established during a prior authentication with another network slice.
