Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.

Wireless device and method for rekeying with reduced packet loss for high-throughput wireless communications

An embodiment of the present invention provides an apparatus, comprising a network interface (NIC) card operable in communication with a mobile platform to monitor network traffic and perform filtering to enable decreased system resource use in said mobile platform when in an Always On Always Connected (AOAC) state.

Techniques for always on always connected operation of mobile platforms using network interface cards

Embodiments of the present invention provide a method and apparatus for a multiple-entity wireless communication adapter, including at least a first connection module to communicate first signal traffic corresponding to a basic service set station entity, a second connection module to communicate second signal traffic corresponding to an entity that is not a basic service set station, and a shared physical layer able to process both the first and the second signal traffic. Additional features are described and claimed.

Method and apparatus of multiple entity wireless communication adapter

A platform to mitigate noise caused by spread spectrum clock signals. The platform may comprise a noise mitigation block, which may include a first set of analog-to-digital converters, a second analog-to-digital, and a noise canceller. The first set of analog-to-digital converters may generate clock samples by digitizing the plurality of spread spectrum clock signals, which are provided as inputs to the noise mitigation block. The second analog-to-digital converter may generate data samples by digitizing the data signal. The noise canceller coupled to the first set of analog-to-digital converters and the second analog-to-digital converter may identify an interference portion in the data signal using the clock samples and the data samples and remove the interference portion from the data signal.

Mitigating noise created by spread spectrum clocks

An embodiment of the present invention provides a network interface card (NIC), comprising an intelligent wake mechanism and a device driver associated with the intelligent wake mechanism and configured to agree with embedded software on a set of wake codes and wake behaviors associated with the wake codes such that when the NIC encounters a wake event, the NIC first adds the wake code to a command queue, then it drives a PME pin to high to wake a device connected to the NIC.

Apparatus and methods using intelligent wake mechanisms

Embodiments of the present invention provide a method and apparatus of performing on one or more bytes of an input data block at least one predetermined encryption or decryption operation.

Method apparatus and system of performing one or more encryption and/or decryption operations

Briefly, a method and apparatus that may enable roaming of a station from a first access point to a second access point by presenting a power saving mode to the first access mode while establishing a secured connection with the second access point.

Method and apparatus of secure roaming

A system and method of providing security mechanisms for securing traffic communicated from a server system to a client system independent of the state of the client system. The server system determines whether the client system has entered an operational state. When the client system is operational, key exchange processes are initiated between the two systems, the results of the key exchange processes being the parameters for use in securing traffic communication between the two systems. The results are stored in the client system. The results are inhibited from being updated in the client system until the server system is successful in completely executing another set of key exchange processes. The results are updated with the results obtained from successful execution of the other set of key exchange processes if the execution of the other set is successful. The traffic communication is thus secured based on whatever results are stored in the client system.

System and method for providing security mechanisms for securing network communication

A multiprocessor data processing system includes a private data bus and a private program bus coupled to each of the processors. Coupled between the private data buses is a plurality of memory banks, each of which can be dynamically switched between the processors to move blocks of data without physically transferring the data from one bank to another. Likewise, a plurality of memory banks is coupled between the program buses. These memory banks are loaded with pages of program instructions from external memory over a shared bus. Any one of the pages can be coupled to either of the processors on its respective private program bus. When the pages are coupled to the shared bus, they appear as a contiguous address space. When a page is coupled to one of the private program buses, the addressing mode is changed so that the page is mapped to a common address space. This permits the program code to be loaded into any available page, and the processors can execute the code regardless of where it has been loaded, thereby permitting easy relocatability.

Memory address translations for programs code execution/relocation

An apparatus and method for arbitrating bus ownership of a first communication bus ('C1-bus') for a plurality of C1-bus masters and arbitrating bus ownership of a second communication bus ('C2-bus') for a plurality of C2-bus masters. The apparatus further performs a DMA transfer, without processor assistance, between a first component coupled to the C1-bus and a second component coupled to the C2-bus.
