  • Publication number: 20240306194
    Abstract: In an IEEE 802.11 wireless system, a wireless STA is configured to access a secondary channel by receiving an inter-BSS PPDU which identifies a transmission channel bandwidth for the inter-BSS PPDU and TXOP duration, and then accessing a secondary channel which excludes the transmission channel bandwidth identified by the inter-BSS PPDU and a primary 20 MHz channel for the wireless STA device from a basic service set (BSS) operating bandwidth associated with the wireless STA device before exchanging one or more frames on the secondary channel during the TXOP duration without using the primary 20 MHz channel for the wireless STA device, and then switching back to the primary 20 MHz channel before the TXOP duration ends.

  • Patent number: 12086246
    Abstract: A method is provided for protecting a machine learning (ML) model from a side channel attack (SCA). The method is executed by a processor in a data processing system. The method includes generating a first random bit. A first weighted sum is computed for a first connection between a node of a first layer and a node of a second layer of the ML model. The first weighted sum for the first connection is equal to a multiplication of the weight of the first connection multiplied by an input to the selected node. In the multiplication, one of the weight or the input is negated conditioned on a value of the random bit. A first output including the computed first weighted sum is provided to one or more nodes of a second layer of the plurality of layers.
