Dynamic offloading of V2X services to DSRC
Systems and methods of providing V2X communications are generally described. The multimode UE communicates V2X messages with an eNB. The eNB detects whether the UE is able to receive messages from a nearby DSRC RSU based on measurements received from the UE and reported to the eNB. Based on the measurements, the eNB offloads V2X traffic to the DSRC RSU and triggers the UE to start communicating the V2X services from the DSRC RSU rather than the eNB. The measurements are reported in a BSR or DSRC MAC control element or RRC measurement report. The measurement report includes DSRC presence fields, CCH measurements and SCH measurements for each DSRC RSU that the UE is able to detect. |

Efficient threat context-aware packet filtering for network protection
A threat intelligence gateway (TIG) may protect TCP/IP networks from network (e.g., Internet) threats by enforcing certain policies on in-transit packets that are crossing network boundaries. The policies may be composed of packet filtering rules with packet-matching criteria derived from cyber threat intelligence (CTI) associated with Internet threats. These CTI-derived packet-filtering rules may be created offline by policy creation and management servers, which may distribute the policies to subscribing TIGs that subsequently enforce the policies on in-transit packets. Each packet filtering rule may specify a disposition that may be applied to a matching in-transit packet, such as deny/block/drop the in-transit packet or pass/allow/forward the in-transit packet, and also may specify directives that may be applied to a matching in-transit packet, such as log, capture, spoof-tcp-rst, etc. Often, however, the selection of a rule's disposition and directives that best protect the associated network may not be optimally determined before a matching in-transit packet is observed by the associated TIG. In such cases, threat context information that may only be available (e.g., computable) at in-transit packet observation and/or filtering time, such as current time-of-day, current TIG/network location, current TIG/network administrator, the in-transit packet being determined to be part of an active attack on the network, etc., may be helpful to determine the disposition and directives that may best protect the network from the threat associated with the in-transit packet. The present disclosure describes examples of methods, systems, and apparatuses that may be used for efficiently determining (e.g., accessing and/or computing), in response to the in-transit packet, threat context information associated with an in-transit packet. The threat context information may be used to efficiently determine the disposition and/or one or more directives to apply to the in-transit packet. This may result in dispositions and/or directives being applied to in-transit packets that better protect the network as compared with solely using dispositions and directives that were predetermined prior to receiving the in-transit packet. |

Shared key generation based on dual clocks
Techniques for computer security, and more specifically timestamp-based key generation techniques, are described. Some implementations provide a table of key generation processes that is shared as a secret between a first computing system and a second computing system, both of which have two clocks. The first clock is a real-time clock and the second clock is a variable-time clock. The variable time clocks are synchronized and run at the same rate, faster or slower than real time. Both computing systems use the same technique for selecting a key generation process from the table, such as based on a random number generator seeded with a timestamp obtained from their variable time clocks. Since the computing systems have synchronized variable-time clocks, they both select and use the same key generation process, thereby generating the same encryption key without the need to communicate the key from one system to another. |

Computer-implemented systems and methods for performing computational tasks across a group operating in a trust-less or dealer-free manner
The invention relates to secure determination of a solution (S) to a computational task by a dealer-free threshold signature group. Access to a resource or reward is offered in exchange for the solution. The method enables individuals in said group to work together in a trust-less, or dealer-free manner. To achieve this, individuals generate their own key pair and use their public key to establish with the group an initial shared public key that they can all use, in parallel, to find a solution to the task. Their own private keys remain secret and, therefore, the collaboration is trust¬less, and operates efficiently, because a verified shared public key is created using the initial shared public key that was used when a solution is found and verified. The resource or reward can be secured by the verified shared public key. Because the private keys of each participant were used in the determination of the initial shared public key that lead to the solution then participants must then collaborate to unlock the resource or reward because the corresponding shared private key can only be generated by all participants or a pre-agreed threshold of participants. Efficiency is achievable by using an initial shared public key and calculating with the group a verified shared public key after the solution has been found. The invention enables the task to be trust-less by using the homomorphic properties of elliptic curve cryptography when applying Shamir's secret sharing scheme.

Insulated gate power device with independently controlled segments
A design technique is disclosed that divides up a cellular power switch into different size segments. Each segment is driven by a different driver circuit. The selection of the combination of segments is made to minimize the combined conduction and switching losses of the power switch. For example, for very light loads, switching losses dominate so only a small segment is activated for driving the load. For medium and high load currents, conduction losses become more significant, so additional segments are activated to minimize the total losses. In one embodiment, the number of cells in the segments is binary weighted, such as 1×, 2×, and 4×, so that there are seven different combinations of segments. The drivers may be configured to achieve the same or different slew rates of the segments, such as to reduce transients. The segments may all be in the same die or a plurality of dies. |

Dynamic time-weighted systems and methods for management of acoustic exposure
Workplace safety is a principal concern in many environments. Protecting user ears from damage due to extended exposure to unacceptably high sound volume serves as an important component to workplace safety.

As provided herein, monitoring a user's sound exposure on one device may cause the sound level presented to the user from a second device to become limited. Additionally, over time the sound level limits may be adjusted based on the cumulative historic sound exposure. As a result, the user may avoid exposure to unacceptably high sound levels originating from more than one source and/or over an extended period of time. |

Method to charge lithium-ion batteries with user, cell and temperature awareness
Lithium-ion cells are widely used in various platforms, such as electric vehicles (EVs) and mobile devices. Complete and fast charging of cells has always been the goal for sustainable system operation. However, fast charging is not always the best solution, especially in view of a new finding that cells need to rest/relax after being charged with high current to avoid accelerated capacity fading. A user aware charging algorithm is proposed which maximizes the charged capacity within a user-specified available charging time (i.e., user-awareness) while ensuring enough relaxation (i.e., cell-awareness) and keeping cell temperature below a safe level. |
