Abstract: Systems and methods provide quantum secured internet transport. Quantum key distribution (QKD) is made universally available to existing Transport Layer Security (TLS) Internet services without requiring modification of existing applications. QKD keys may be prefetched and transferred to user devices at secure sites using QKD over an optical link (e.g., a continuous wave fiber or free-space optical link). A proxy QKD TLS tunnel client and a QKD TLS tunnel server are transparent to the user devices and select QKD keys for use with existing TLS client and TLS server services to form a QKD TLS tunnel between the user devices for secure communication. One-time-pad (OTP) encryption uses pre-shared QKD keys to provide secure OTP based encryption.

Abstract: The present disclosure generally relates to systems, methods and software for determining an optimal burst transmission time through a modem, such as a cable modem, a wireless access point, a node in a cable network, or a satellite communication link. Particularly, the present disclosure makes it possible for a burst of queued data, defined as data above a certain percentile of a monitored traffic rate, to be transmitted by the modem at a time that provides the best chance of avoiding a collision with a co-occurring burst of data from another user connected to the same modem. In an embodiment, the systems, methods and software disclosed herein use the optimal transmission time to replace a contention window transmission time, at least for bursty data, or they completely eliminate the need for contention windows, at least for bursty data.

Abstract: A wireless communication network includes a plurality of first electronic devices configured for wireless communication, at least one second electronic device configured for wireless communication, and at least one access point configured to wirelessly receive client data from, and transmit network data to, the plurality of first electronic devices and the at least one second electronic device. The wireless communication network further includes a virtual private wireless communication sub-network that includes the plurality of first electronic devices and excludes the at least one second electronic device. The virtual private wireless communication sub-network is configured to enable each of the plurality of first electronic devices to automatically connect with the wireless communication network.

Abstract: The telecommunications systems, software, and methods are for power-efficient coordinated multipoint transmission, particularly in millimeter-wave small cells. The systems, software, and methods apply portfolio theory to determine an allocation of power to a plurality of transmitters in communication with one or more receivers in a joint transmission configuration, such as a MMW or BF-MMW joint transmission configuration. The systems, software, and methods apply portfolio theory to determine an allocation of power to a plurality of transmitters such that a mean received power, associated with a certain level of variance, is maximized, or the variance of received power, associated with a certain level of mean received power, is minimized.

Abstract: A first node of a network includes a quantum transmitter, a classical transceiver, and an initial-key generator that cooperate with a second node to transmit an initial key via the quantum transmitter. The first node includes a key-series generator that (i) encrypts a first unencrypted key of a series of unencrypted keys to generate a first encrypted key of a series of encrypted keys and (ii) encrypts each subsequent unencrypted key of the series of unencrypted keys with a preceding unencrypted key of the series of unencrypted keys to generate a subsequent encrypted key of the series of encrypted keys. The encrypted keys are transmitted to the second node. The first node includes one or both of a decryptor and an encryptor. The decryptor decrypts encrypted data using a last unencrypted key of the series of unencrypted keys. The encryptor encrypts unencrypted data using the last unencrypted key.

Abstract: An ad-hoc wireless network is implemented by a plurality of wireless access points to detect and report failure of a concurrently implemented conventional network. The wireless access points collect and store network status information of the conventional network and send the network status information to a centralized emergency manager when failure of the conventional network is detected. The ad-hoc wireless network may also provide backhaul connectivity to a wireless access point of the failed conventional network for emergency communication.
