Abstract: The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

Abstract: A method of generating a verification code includes generating a plurality of first photons and a plurality of second photons that are entangled in a first basis, which is time, and entangled in a second basis comprising a first and second state. The plurality of first photons are provided to a first device where the arrival time and an associated first or second state of the plurality of first photons are measured. An ordered list of the measured time of arrival of the plurality of first photons are generated at the first device. The plurality of second photons are provided to a second device. A time of arrival and an associated first or second state of the plurality of second photons are measured at the second device. An ordered list of the measured time of arrival of the plurality of second photons are generated at the second device.

Abstract: An entangled quantum cache includes a quantum store that receives a plurality of quantum states and is configured to store and order the plurality of quantum states and to provide select ones of the stored and ordered plurality of quantum states to a quantum data output at a first desired time. A fidelity system is configured to determine a fidelity of at least some of the plurality of quantum states. A classical store is coupled to the fidelity system and configured to store classical data comprising the determined fidelity information and an index that associates particular ones of classical data with particular ones of the plurality of quantum states and to supply at least some of the classical data to a classical data output at a second desired time. A processor is connected to the classical store and determines the first time based on the index.

Abstract: An entangled quantum state receiver includes an optical detector that generates an electrical signal having a signal characteristic in response to detection of a single photon. A first electrical circuit generates an electrical signal having a predetermined duration at an output when the signal characteristic is present. A clock generates a clock with a period, wherein the predetermined duration is greater than the period. A second electrical circuit generates and stores a state or a time in a memory location, where the state has a first state value when the electrical signal having the predetermined duration is present during a clock cycle and has a second state value when the electrical signal having the predetermined duration is not present during the clock cycle. A processor determines received entangled state information from the state value stored in the memory location or from time stored in the memory location.

Abstract: Method and apparatus for synchronizing and locking clocks identifies entangled pairs of photons by comparing a first and second list of measured state values of single photons, wherein the first list is compiled by photon arrival times measured using a first clock and the second list is compiled by photon arrival times measured using a second clock. Entangled pairs of photons are identified by a match of the measured state values of single photons in their respective lists. Elapsed times of the first and second clocks are determined by taking the difference between arrival times of respective identified entangled pairs of photons measured using their respective clocks. A rate of one of the first and second clocks is changed based on a difference between the elapsed times, thereby synchronizing the first and second clocks. Clocks are locked by repeating.

Abstract: The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

Abstract: An identity verification system enables the identity of an individual to be verified to others using the internet. An initial identification ceremony is recorded in which the user performs instructions that cannot be known in advance, such as reading text that cannot be anticipated. The initial ceremony can be replayed and authenticated by individuals who already personally know the user. Alternatively, the identity of the user in the initial ceremony can be authenticated using other existing techniques such as KBA. A secondary instruction ceremony is subsequently performed when identity verification is required in order to authorize a directive or transaction. In the secondary instruction ceremony the user performs unforeseeable instructions such as reading text that cannot be anticipated and reading aloud an indication of the transaction.

Abstract: A system and method for securing communications in a wireless network includes the steps of authenticating members of the wireless network, generating a member private key to be used by the members of the wireless network, and distributing the member private key to each of the members of the wireless network. A member is authenticated based on the ability of the member to be physically proximate to at least one other member of the wireless network at a given instant. The member private key is generated by one of the members, hereinafter referred to as a master member, in response to a changing value stored at the one of the members. The member private key is then securely distributed to each of the members in the WLAN network.

Abstract: A client device detects when it roams between subnets and signals to a device in the subnet being entered. The client may detect roaming by monitoring subnet identifiers included in beacon signals transmitted by access points. When the client detects a beacon with a new subnet identifier and at the same time no longer detects a beacon with the original subnet identifier then roaming is indicated. When roaming is indicated the client responds by setting a tag, such as an IEEE 802.1q VLAN tag, in packets transmitted by the client. The tagged packets provide an indication to devices in the new subnet that the client has roamed into that new subnet. Devices in the new subnet, such as access points and switches, recognize the tagged packets and establish a path to the original subnet in response. For example, the tagged packets transmitted by the client may be encapsulated pursuant to a Layer 3 protocol and tunneled from a switch associated with the subnet being entered to a switch in the original subnet.
