    Abstract: This disclosure describes techniques for device to device authentication. For instance, a first device may detect a second device, such as when a user physically attaches the second device to the first device or when the second device wireless communicates with the first device. A component of the first device and/or an authentication entity may then determine to authenticate the second device. In some instances, the component determines to authenticate the second device using information associated with an environment of the second device. To authenticate the second device, the authentication entity may send a request to a user, receive a response from the user, and then verify the response. After the authentication, the first device may determine that the second device includes a trusted device and establish a connection with the second device.

    Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

    Abstract: Broadcast energy and spectrum consumption optimization may be provided. It may be determined, by a computing device for each of a plurality of client devices, a corresponding plurality of respective minimum Modulation and Coding Schemes (MCSs) needed to reach each of the respective plurality of client devices from the computing device at a predetermined power level. Next, an optimal MCS from the plurality of respective minimum MCSs may be used to reach a first group of the plurality of client devices via broadcast. Then unicast may be used to reach a second group of the plurality of client devices wherein the optimal MCS is selected to minimize the total amount of airtime used for the broadcast and the unicast.

    Abstract: Systems and methods may include sending, to a network registrar, an extended duplicate address request (EDAR) message including a first nonce generated by a host computing device, and receiving, from the network registrar, an extended duplicate address confirmation (EDAC) message including a second nonce and a first signature, a first nonce pair including the first nonce and the second nonce being signed by the network registrar via a first key pair of the network registrar via the first signature. The systems and methods may further include sending a first neighbor advertisement (NA) message to the host computing device including the second nonce. The second nonce and a public key of the network registrar verifies the first signature from the network registrar, the verification of the first signature indicating that a router through which the host computing device connects to a network is not impersonating the network.

    Abstract: Techniques for leveraging MLD capabilities at edge nodes of network fabrics to receive SNMAs from silent hosts, and creating unicast addresses from the SNMAs for the silent nodes that are used as secondary matches in a network overlay if primary unicast address lookups fail. The edge nodes described herein may act as snoopers of MLD reports in order to identify the SNMAs of the silent hosts. The edge nodes then forge unicast addresses for the silent hosts that match with the least three bytes of the SNMAs. The forged unicast addresses are presented as unicast MAC/IP mappings in the fabric overlay. In situations where a primary IP address lookup fails, the look-up device performs a secondary lookup for a mapped address that has the last three bytes of the IP address. If a mapping is found, the lookup is sent as a unicast message to the matching MAC address.

    Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a random IP address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a random IP address that cannot be used to identify the endpoint device or service. The client device may then communicate data packets to the server using the random IP address as the destination address, and a gateway that works in conjunction with DNS can convert the random IP address to the actual IP address of the server using NAT and forward the data packet onto the server.
