Abstract: The technology disclosed herein enables an auxiliary device to run a service that can access and analyze data of a Trusted Execution Environment (TEE). The auxiliary device may establish an auxiliary TEE in the auxiliary device and establish a trusted communication link between the auxiliary TEE and the TEE (i.e., primary TEE). The primary TEE may execute a target program using the primary devices of a host device (e.g., CPU) and the auxiliary TEE may execute a security program using the auxiliary device (e.g., DPU). In one example, the primary and auxiliary TEEs may be established for a cloud consumer and the auxiliary TEE may execute a security service that can monitor data of the primary TEE even though the data is inaccessible to all other software executing external to the primary TEE (e.g., inaccessible to host operating system and hypervisor).

Abstract: Apparatuses, systems, and techniques for detecting that one or more computer programs executed by a host device are subject to malicious activity using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface. The integrated circuit hosts a hardware-accelerated security service to protect one or more computer programs executed by the host device. The security service extracts a set of features from data stored in the physical memory, the data being associated with the one or more computer programs. The security service determines, using the ML detection system, whether the one or more computer programs are subject to malicious activity based on the set of features. The security service outputs an indication of the malicious activity responsive to a determination that the one or more computer programs are subject to the malicious activity.

Abstract: Apparatuses, systems, and techniques for classifying one or more computer programs executed by a host device as being ransomware using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface. The integrated circuit hosts a hardware-accelerated security service to protect one or more computer programs executed by the host device. The security service obtains a series of snapshots of data stored in the physical memory and extracts a set of features from each snapshot of the series of snapshots, each snapshot representing the data at a point in time. The security service classifies a process of the one or more computer programs as ransomware or non-ransomware using the set of features and outputs an indication of ransomware responsive to the process being classified as ransomware.

Abstract: Apparatuses, systems, and techniques for classifying one or more candidate uniform resource locators (URLs) as having a domain generation algorithm (DGA) domain using a machine learning (ML) detection system. An integrated circuit is coupled to physical memory of a host device via a host interface. The integrated circuit hosts a hardware-accelerated security service to protect one or more computer programs executed by the host device. The security service extracts a set of features from data stored in the physical memory, the data being domain characters in one or more candidate URLs. The security service classifies, using the ML detection system, the one or more candidate URLs as having a DGA domain or a non-DGA domain using the set of features. The security service outputs an indication of a DGA malware responsive to the one or more candidate URLs being classified as having the DGA domain.

Abstract: A medical probe includes a generally tubular member with a tip portion coupled to the tubular member. A puller wire is disposed in the tubular member and configured for movement along the longitudinal axis to bend the tip portion with respect to the longitudinal axis.

The t-bar includes a generally transverse extension and a ferrule connected to the puller wire. The probe includes a fiber engaged to the generally transverse extension and extending distally into the probe to increase a strength of the anchor with respect to forces applied to the puller wire to deflect the tip of the medical probe.

The fiber aligner and the fiber holding portion are relatively movable in the alignment direction of the optical fibers.

Abstract: The present invention relates to methods for secure computation and/or communication. Entangled photons (118) are generated such that each participating party receives a series of optical pulses. Each party has private information (110, 112) which are never transmitted through public or private communication channels. Instead, each party converts their respective private information (110, 112) into measurement bases via an encryption process (114, 116) which are then applied to the entangled photons (118). After the measurement process, e.g., quantum frequency conversion (122, 124), reference indices are announced (124, 126) so that computation can be performed (128) without revealing the private information directly or indirectly.
