Approaches presented herein provide for unsupervised domain transfer learning. In particular, three neural networks can be trained together using at least labeled data from a first domain and unlabeled data from a second domain. Features of the data are extracted using a feature extraction network. A first classifier network uses these features to classify the data, while a second classifier network uses these features to determine the relevant domain. A combined loss function is used to optimize the networks, with a goal of the feature extraction network extracting features that the first classifier network is able to use to accurately classify the data, but prevent the second classifier from determining the domain for the image. Such optimization enables object classification to be performed with high accuracy for either domain, even though there may have been little to no labeled training data for the second domain.

Techniques for equipping mobile devices with two different types of wireless communication devices, one of which is part of a mesh network that can serve as a backup path for transmitting data to the internet. The mobile devices, such as mobile carts, can dynamically switch to the mesh network if Wi-Fi connectivity fails or becomes weak. This dual-network approach improves data transmission reliability, reduces dependence on a single network type, and ensures continuous operation, which can be important in certain environments, such as healthcare settings.

Approaches presented herein provide systems and methods for content generation systems that incorporate a denoising diffusion generative adversarial network (DDGAN) into a content generation pipeline. A generator associated with the DDGAN may be conditioned on a set of input images that include at least a noisy image from a diffusion engine, an upsampled low resolution image, and a historical image. The generator may be used to generate an output image having one or more properties that are different from a content engine. Weights for the generator may be determined during a training process that includes a discriminator that evaluates at least the noisy image, the upsampled low resolution image, and a noised image produced from the output image.

Approaches are described herein for secure masking of channel activity for transmission security (TRANSEC) enabled terminals in satellite communication networks. Embodiments include techniques for masking channel activity at the link-layer in the outroute and / or in the inroute. For example, in the outroute, embodiments encapsulate packet data units (PDUs) using a TRANSEC-compatible stream encapsulation protocol. In the inroute, embodiments encapsulate burst transmissions using a TRANSEC-compatible inroute burst encapsulation protocol. Outroute and / or inroute activity can be further masked by creating the impression of constant-rate traffic, constant-rate bandwidth allocations, and the like.

Approaches are described herein for link-layer address concealment for transmission security (TRANSEC) enabled (TE) terminals in satellite communication networks. For example, TE terminals can randomly select a proposed masked system assigned identifier (mSAI), which is a temporary identifier different from any real identifiers of the terminal (e.g., a real SAI, real electronic serial number, etc.). The ground station (e.g., inroute group manager) checks availability of the mSAI. If available, the request is acknowledged, the mSAI is assigned to the terminal, and bandwidth is allocated to the terminal using the mSAI. Subsequent allocated bursts can be sent by the terminal using the allocated bandwidth based on the mSAI. Some embodiments include techniques for handling requests for an unavailable mSAI, simultaneous requests by different terminals for the same mSAI, periodic changes of mSAIs for added security, and use of mSAI-related timers to support additional features.

Approaches presented herein provide for the attestation of devices in managed networks, in order to verify state and establish trust in those devices as well as in the managed network and / or subnets. The devices in a network, including devices such as network switches, can perform self-attestation by transmitting attestation evidence using one or more network messages. One or more verifiers can verify the attestation evidence and determine which devices or subnets are trusted. Data and messages can then be routed along trusted paths through a trusted network or subnet, such that all devices along those paths are trusted devices. In order to reduce the volume of attestation traffic for large networks, a network device can provide attestation evidence to a verifier that is connected to that device, rather than propagating all evidence for all devices to a single verifier. Once verified, a list of trusted devices can be propagated rather than the instances of evidence that were used for the verification.

Approaches are described herein for securely initializing a TRANSEC-enabled terminal (TET) in a satellite communication network. At a secure location, a unique Terminal Master Key and Electronic Serial Number, are securely burned into the terminal's memory. Upon booting, the terminal verifies its identity using a signed TE file and encrypted keys. When deployed, the terminal initially sends an unallocated burst with a fake ESN to obtain bandwidth allocation (e.g., from an inroute bandwidth allocator). The terminal proceeds with an initial association request using a randomly generated identifier, followed by a transport-layer-secure registration process (e.g., with a network management system over HTTPS). After successful registration, the TET receives link-layer key materials and shifts to using its real ESN with link-layer security (LLS) for subsequent communications.

This invention discloses a wind farm fault voltage recovery method based on topology reconstruction. The proposed method utilizes a radial network for both normal operation and fault isolation of the wind farm. Topology-level optimization calculations enable the wind farm to achieve both the low redundancy and high reliability of traditional radial and ring networks. Compared to the traditional radial network approach where circuit breakers directly disconnect during internal faults, the proposed topology reconstruction method ensures both the recovery of voltage at the wind turbine generator terminals and the continued power supply from downstream wind turbines without disconnecting from the grid.
