摘要： In order to enable dynamic scaling of network services at the edge, novel systems and methods are provided to enable addition of add new nodes or removal of existing nodes while retaining the affinity of the flows through the stateful services. The methods provide a cluster of network nodes that can be dynamically resized to handle and process network traffic that utilizes stateful network services. The existing traffic flows through the edge continue to function during and after the changes to membership of the cluster. All nodes in the cluster operate in active-active mode, i.e., they are receiving and processing traffic flows, thereby maximizing the utilization of the available processing power.

摘要： This document describes apparatuses, systems, and techniques directed to a modular system validation platform for computing devices. The modular system validation platform includes an interface board for interfacing a host with a peripheral. The interface board includes an apparatus identifier, a first connector configured to couple to the host, and a second connector configured to couple to the peripheral. The interface board comprises interface circuitry that can be reconfigured to enable different peripherals to operate with the host using the same interface board. The interface circuitry enables the interoperability between the host and the peripheral by distributing power from the host to the peripheral and facilitating communications between the host and the peripheral. By using the reconfigurable interface board to test and troubleshoot the interoperability of the processor and the peripheral, resources, time and costs spent during the design and testing phases of computing devices may be minimized.

摘要： Novel tools and techniques might provide for implementing Internet of Things (“IoT”) functionality, and, in particular embodiments, implementing added services for OBD2 connection for IoT-capable vehicles. In various embodiments, a portable device (when connected to an OBD2 DLC port of a vehicle) might monitor wireless communications between a vehicle computing system(s) and an external device(s), might monitor vehicle sensor data from vehicular sensors tracking operational conditions of the vehicle, and might monitor operator input sensor data from operator input sensors tracking input by a vehicle operator. The portable device (or a server) might analyze either the monitored wireless communications or a combination of the monitored vehicle sensor data and the monitored operator input sensor data, to determine whether vehicle operation has been compromised. If so, the portable device (or the server) might alert the operator of the vehicle via a user interface, and might initiate one or more remediation operations.

摘要： A method for obfuscating data at-transit can include receiving, at a first component on a chip, an instruction request for communicating a first data to a second component on the chip. The first component can be a processor and the second component can be an associated memory. The method can further include, determining a sequence of data arranged to obfuscate the first data while including valid bits of the first data, wherein the sequence of data indicates what is to be conveyed across lines on the chip during each time slot over a window of time controlled by a clock signal on the chip; and providing, over the window of time, the first data to the second component across the lines on the chip according to the sequence of data.

摘要： An apparatus to facilitate scalable runtime validation for on-device design rule checks is disclosed. The apparatus includes a memory to store a contention set, one or more multiplexors, and a validator communicably coupled to the memory. In one implementation, the validator is to: receive design rule information for the one or more multiplexers, the design rule information referencing the contention set; analyze, using the design rule information, a user bitstream against the contention set at a programming time of the apparatus, the user bitstream for programming the one or more multiplexors; and provide an error indication responsive to identifying a match between the user bitstream and the contention set.

摘要： An integrated-circuit device comprises a processor, a hardware key-storage system, and a key bus. The hardware key-storage system comprises a non-volatile key storage memory, which includes a key register, for storing a cryptographic key, and an address register, for storing a destination memory address for the cryptographic key. The hardware key-storage system further comprises output logic for sending the cryptographic key over the key bus to the destination memory address, and write-once logic for preventing an address being written to the address register unless the address register is in an erased state.

摘要： Techniques are provided for actively controlling a communications bus to mitigate threats, including cyber-attacks. A methodology implementing the techniques according to an embodiment includes detecting a threat in a message that is being transmitted between nodes on the communications bus. The message comprises one or more message frames and the threat detection is based on analysis of an initial portion of the message frame. The method further includes actively controlling the bus, based on the threat detection, to prevent the remaining portion of the message frame from delivering the threat to one or more of the nodes on the bus. Actively controlling the bus includes isolating nodes from the bus and/or overwriting data in the remaining portion of the message frame to invalidate the message frame or to remove the threat from the message frame.

摘要： An apparatus to facilitate transparent network access controls for spatial accelerator device multi-tenancy is disclosed. The apparatus includes a secure device manager (SDM) to: establish a network-on-chip (NoC) communication path in the apparatus, the NoC communication path comprising a plurality of NoC nodes for ingress and egress of communications on the NoC communication path; for each NoC node of the NoC communication path, configure a programmable register of the NoC node to indicate a node group that the NoC node is assigned, the node group corresponding to a persona configured on the apparatus; determine whether a prefix of received data at the NoC node matches the node group indicated by the programmable register of the NoC; and responsive to determining that the prefix does not match the node group, discard the data from the NoC node.

摘要： An approach for operating at least one touch-sensitive, flat input device of a complete device, the input device being connected via a message-based bus connection to a control device of the complete device, and messages containing touch datasets describing touch data events being transmitted to the control device, which evaluates the messages for input information for an application program implemented by the control device, wherein when a security function in the control device that queries sensitive input information is accessed, the touch datasets are transmitted from the input device to the control apparatus via the bus connection in encrypted form until the associated input process has ended.
