  • Patent number: 11824980
    Abstract: This disclosure describes systems, methods, and devices related to security for multi-link operations. A multi-link device (MLD) may establish a first communication link between a first device of the MLD and a first device of a second MLD, and a second communication link between a second device of the MLD and a second device of the second MLD. The MLD may generate a group-addressed message. The MLD may protect the group-addressed message using a first key or a first integrity key. The MLD may protect the group-addressed message using a second key or a second integrity key. The MLD may send, using the first communication link, the group-addressed message protected using the first key or the first integrity key, and may send, using the second communication link, the group-addressed message protected using the second key or the second integrity key.

  • Patent number: 11824890
    Abstract: A threat detection system for detecting malware can automatically decide, without manual expert-level interaction, the best set of features on which to train a classifier, which can result in the automatic creation of a signature-less malware detection engine. The system can use a combination of execution graphs, anomaly detection and automatic feature pruning. Execution graphs can provide a much richer structure of runtime execution behavior than conventional flat execution trace files, allowing the capture of interdependencies while preserving attribution (e.g., D happened because of A followed by B followed by C). Performing anomaly detection on this runtime execution behavior can provide higher order knowledge as to what behaviors are anomalous or not among the sample files. During training the system can automatically prune the features on which a classifier is trained based on this higher order knowledge without any manual intervention until a desired level of accuracy is achieved.

  • Patent number: 11822644
    Abstract: Technologies for memory management with memory protection extension include a computing device having a processor with one or more protection extensions. The processor may load a logical address including a segment base, effective limit, and effective address and generate a linear address as a function of the logical address with the effective limit as a mask. The processor may switch to a new task described by a task state segment extension. The task state extension may specify a low-latency segmentation mode. The processor may prohibit access to a descriptor in a local descriptor table with a descriptor privilege level lower than the current privilege level of the processor. The computing device may load a secure enclave using secure enclave support of the processor. The secure enclave may load an unsandbox and a sandboxed application in a user privilege level of the processor. Other embodiments are described and claimed.

  • Patent number: 11818002
    Abstract: A wireless sensor preferably has a case which is intrinsically safe and has no exposed parts which can become not intrinsically safe due to the passage of time or through contact with chemicals typically encountered in a location where the wireless sensor is used. It preferably has no integral visual display other than lights, and it preferably includes at least one signal light. The sensor preferably includes a wireless transceiver for allowing remote read and remote control of the sensor. The sensor preferably includes piezoelectric pressure detectors for allowing a user to locally interact with the sensor by pressing on the case. Data can be automatically harvested from the sensors by a portable electronic data-retrieving device which is usually geographically remote from the sensors when the portable electronic data-retrieving device and the sensors are in range of a wireless system which allows them to communicate when they are geographically proximate each other.

  • Patent number: 11805415
    Abstract: In embodiments of the present disclosure, there is provided a method for authenticating an access point. In the method, a request for joining a network is received from an access point. A neighbor authentication notification is transmitted to the access point for obtaining an authentication code from a neighbor access point that is connected in the network in accordance with a determination that the access point is verified. The authentication code that is generated by the neighbor access point is received from the access point. The access point is accepted to join the network in accordance with a determination that the authentication code is valid. Embodiments of the present disclosure present a safe and effective way for authenticating the access point that is requesting to join the network, which provides enhanced authentication and increases the security level of the network.

  • Patent number: 11782849
    Abstract: A processor includes a decode unit to decode an instruction that is to indicate a page of a protected container memory, and a storage location outside of the protected container memory. An execution unit, in response to the instruction, is to ensure that there are no writable references to the page of the protected container memory while it has a write protected state. The execution unit is to encrypt a copy of the page of the protected container memory. The execution unit is to store the encrypted copy of the page to the storage location outside of the protected container memory, after it has been ensured that there are no writable references. The execution unit is to leave the page of the protected container memory in the write protected state, which is also valid and readable, after the encrypted copy has been stored to the storage location.

  • Patent number: 11765155
    Abstract: Systems and methods are disclosed to implement an application that can automatically download new digital certificates to verify signed code updates received by the application. In embodiments, under normal circumstances, the application uses a pinned certificate in the application's executable code to verify received updates signed using the certificate. However, if the code signing certificate changes, the application will automatically retrieve the new certificate from a certificate publishing service. Accordingly, the new certificate does not have to be included as part of the code update package, and the retrieval of the new certificate can be managed more robustly by the application updater. In embodiments, downloads from the certificate publishing service may be secured using a nonce and a shared secret that is known to the service and also pinned to the application. In this way, the download process can be protected from hijacking attacks.
