Abstract: The present invention relates to core shell liquid metal encapsulates comprising multi-functional ligands, networks comprising such encapsulates and processes of making and using such encapsulates and networks. When subjected to strain, such network's conductivity is enhanced, thus allowing the network to serve as a healing agent that restores at least a portion of the conductivity in an adjacent conductor.

Abstract: A processor for mitigating side channel attacks includes units that perform fetch, decode, and execution of instructions and pipeline control logic. The processor performs speculative and out-of-order execution of the instructions. The units detect and notify the control unit of events that cause a change from a first translation context (TC) to a second TC. In response, the pipeline control logic prevents speculative execution of instructions that are dependent in their execution on the change to the second TC until all instructions that are dependent on the first TC have completed execution, which may involve stalling their dispatch until all first-TC-dependent instructions have at least completed execution, or by tagging them and dispatching them to execution schedulers but preventing them from starting execution until all first-TC-dependent instructions have at least completed execution. The processor may also in response prevent speculative instruction fetching and/or perform speculative instruction flushing.

Abstract: In one embodiment, a method by an Energy processing Unit (EPU) of a computing system includes detecting an event that triggers an integrity verification on a block of the local memory, determining that a hash for the block of the local memory is available, causing data corresponding to the block of the local memory to be read from a source location in response to the determination, performing an in-line hash operation on the data corresponding to the block of the local memory, and comparing an output of the in-line hash operation and a known hash for the block of the local memory.

Abstract: Aspects of the present disclosure relate to techniques for minimizing the effects of RowHammer and induced charge leakage. In examples, systems and methods for preventing access pattern attacks in random-access memory (RAM) are provided. In aspects, a data request associated with a page table may be determined to be a potential security risk and such potential security risk may be mitigated by randomly selecting a memory region from a subset of memory regions, copying data stored in a memory region associated with a page table entry in the page table to the second memory region, disassociating the second memory region from the subset of memory regions and associating the memory region associated with the page table to the second memory region, and updating the page table entry in the page table to refer to the second memory region.

Abstract: A virtualization host is identified for an isolated run-time environment. One or more records generated at a security module of the host, which indicate that a first phase of a multi-phase establishment of an isolated run-time environment has been completed by a virtualization management component of the host, is transmitted to a resource verifier. In response to a host approval indicator from the resource verifier, the multi-phase establishment is completed at the virtualization host.

Abstract: A method includes analyzing, via a first capturing agent, packets processed in a first environment associated with a first host to yield first data. The method includes analyzing, via a second capturing agent, packets processed by a second environment associated with a second host to yield second data, collecting the first data and the second data at a collector to yield aggregated data, transmitting the aggregated data to an analysis engine which analyzes the aggregated data to yield an analysis. Based on the analysis, the method includes identifying first packet loss at the first environment and second packet loss at the second environment.

Abstract: The present disclosure is generally related to a data processing system to detect potential exfiltration of audio data by agent applications can include a data processing system. The data processing system can identify, from an I/O record, an input received from the digital assistant application via a microphone of a client device, an output received from the agent application after the input, and a microphone status for the microphone. The data processing system can determine that the output is terminal based on the input and the output. The data processing system can identify the microphone status as in the enabled state subsequent to the input. The data processing system can determine that the agent application is unauthorized to access audio data acquired via the microphone of the client device based on determining that the output is terminal and identifying the microphone status as enabled.

Abstract: A function is decomposed into a plurality of function shares. The function returns a Boolean result based on whether an input y satisfies a query on a data set. The function shares hide the function from non-collaborating entities that separately execute the function shares. Each of the functions shares are sent to one of a plurality of servers having a same data set. The function shares are executed on the data set at the servers to obtain a respective plurality of shares. A conditional disclosure of secrets operation is simulated on the shares and the input y. The conditional disclosure of secrets operation uses a secret known to at least one of the servers, and further uses a source of randomness shared between the servers. A Boolean value corresponding to the Boolean result is returned based on the conditional disclosure of secrets operation returning the secret.
