  • Publication number: 20180062854
    Abstract: A new approach is proposed to support monitoring Perfect Forward Secrecy (PFS) network traffic by utilizing a hardware security module (HSM) appliance. Here, the HSM appliance is a high-performance, Federal Information Processing Standards (FIPS) 140-compliant security hardware with embedded firmware, which can be used for management and sharing of ephemeral keys used in a secured PFS communication session between two parties. Specifically, the HSM allows a server to share one or more of its ephemeral keys and/or parameters used in PFS traffic during the session with a third party under specified access rights and/or authorization, wherein the third party can be but is not limited to a traffic monitoring module. The HSM allows the third party to access the ephemeral keys stored on the HSM under the specified access rights and/or authorization so that the third party may decrypt and run analytics on the PFS traffic captured during the session.

    Abstract: A transmission assembly for mounting to an external power-source includes an input shaft configured to receive power-source torque. The transmission assembly also includes an output member configured to transmit a transmission output torque to drive a load. The transmission assembly additionally includes a countershaft driven by and arranged parallel to the input shaft. The countershaft has a first gear-set rotatably mounted thereon and is configured to drive the output member. The transmission assembly also includes a second gear-set in mesh with the first gear-set and operatively connected to the output member. Furthermore, the transmission assembly includes an electric motor configured to be selectively connected to the input shaft via a first torque transfer device and to the output member via a second torque transfer device to thereby provide a variable electric motor internal torque input to the transmission assembly. A vehicle having such a transmission and power-source is also disclosed.

  • Publication number: 20170257384
    Abstract: Architectures and techniques for in-app behavior detection. A behavior detection agent within an application running on a hardware computing device captures events within the application. The events are inputs received from one or more sources external to the application. The behavior detection agent generates an event stream from the captured events. The behavior detection agent analyzes the event stream for significant feature frequencies and associations corresponding to one or more attack profiles. The behavior detection agent initiates an attack response in response to finding one or more significant feature frequencies and associations. The attack response comprises at least changing an operational configuration of the application.
