摘要： A network device includes a first transceiver configured to wirelessly receive a first packet from a second transceiver via a channel. The second transceiver is in a wireless device separate from the network device. A circuit is configured to determine a condition of the channel based on the first packet. The circuit has an inactive state and an active state. Elements of the circuit are powered while the circuit is in the active state. The elements of the circuit are not powered while the circuit is in the inactive state. A controller is configured to transition the circuit from the inactive state to the active state in response to the first transceiver wirelessly receiving the first packet, and return the circuit to the inactive state responsive to the circuit having completed determining the condition of the channel.

摘要： An apparatus and corresponding method and computer program comprises a key mixing circuit to generate N groups of AES Blocks, each generated based upon a key, a transmitter MAC address, and a start value for a packet number. An input circuit receives N encrypted MPDUs, each comprising the transmitter address and one of N values for the packet number. Each of the N values for the packet number is greater than, or equal to, the start value for the packet number. A decryption circuit decrypts each of the N encrypted MPDUs using the respective one of the N groups of AES Output Blocks. The key mixing circuit generates each of the N groups of AES Output Blocks before the input circuit receives the respective one of the N encrypted MPDUs. The predetermined start value is initialized when the apparatus is initialized and incremented when each of the N groups of AES Output Blocks is generated.
