Abstract: Methods and apparatus for secure networking protocol optimization via NIC hardware offloading. Under a method, security offload entries are cached in a flow table or a security database offload table on a network interface coupled to a host that implements a host security database mapping flows to Security Association (SA) contexts. Each security offload entry includes information identify a flow and information, such as an offset value, to locate a corresponding entry for the flow in the host security database. Hardware descriptors for received packets that belong to flows with matching security offload entries are generated and marked with the information used to locate the corresponding entries in the host security database. The hardware descriptors are processed by software on the host and the location information is used to de-reference the location of applicable entries in the host security database.

Abstract: A trellis coded modulator and method for generating an encoded word from an input word. The TCM has a first logic branch configured to generate a data portion of the encoded word; and a second logic branch, coupled in parallel with the first logic branch, and configured to generate a corresponding parity portion of the encoded word sequentially after the generation of the data portion of the encoded word.

Abstract: In one embodiment, an apparatus of a wireless communication device includes control circuitry to cause receiver circuitry of the wireless communication device to switch between an on-mode and an off-mode. The apparatus also includes synchronizing circuitry to: perform a correlation on signals of a packet received by the receiver circuitry when in the on-mode to detect a pattern in the received signals, and cause the control circuitry to hold the receiver circuitry in the on-mode based on detection of the pattern in the received signals. The apparatus further includes demodulation circuitry to process additional signals of the packet received by the receiver circuitry when held in the on-mode.

Abstract: For example, a wireless communication device may be configured to determine a count of one or more unreliable data symbols in a received wireless communication packet having a valid Cyclic Redundancy Check (CRC) result; based on the count of the unreliable data symbols, to determine whether to classify the valid CRC result as a false-positive CRC result; and, based on classification of the valid CRC result as a false-positive CRC result, to handle the received wireless communication packet as having a non-valid CRC result.
