Abstract: Embodiments of the disclosure provide distributed authentication with network segmentation and dynamic authorization for networks. The system may include a device within a network of devices. An identifier is within the device and includes a cryptographic certificate. The device is configured to transmit the identifier to an authenticator as a security proof. The authenticator is configured to disable the device from performing at least one operation within the network before verifying an identity of the device via the identifier.

Abstract: Embodiments of the disclosure provide a system and methodology for secure coexistence between wireless fidelity and cellular networks. Methods include: determining whether a wireless fidelity (WiFi) device is sharing a spectrum of a network; and adjusting a parameter of a cellular device sharing the spectrum in response to determining that the WiFi device is sharing the spectrum, wherein the parameter includes a modulation and coding scheme or a transmission power of the cellular device. Methods further include controlling admission of users to a communications network, including: determining whether an incoming transmission is an authentication request from a new user; issuing a temporary authentication to the user to transmit a set of access requirements to the user; determining whether a reply from the user complies with the set of access requirements; and issuing a long-term authentication to the user in response to the reply complying with the set of access requirements.

Abstract: Embodiments of the present disclosure relate to routing data through a distributed communications network (DCN) including several communication devices. Each communication device may include or be in communication with a computing device which causes the communication device to perform actions including: calculate a utility score for a subset of the plurality of communication devices, the utility score quantifying transmissibility of a data packet from the transceiver assembly to another communication device. The utility score may be calculated based on: a distance between the transceiver assembly and the communication device, a transmission queue at the transceiver assembly, a remaining life of the power source, a power consumption to transmit the data packet to the communication device, and a data throughput of the communication device. The computing device may generate instructions to transmit the data packet to at least one communication device in the subset, based on the calculated utility score.
