Certain aspects of the present disclosure provide a method that comprises receiving, from a first node, a neighbor solicitation (NS) message via a virtual link, wherein the NS message is configured to provide an indication of a request to communicate with a second node, and request one or more communication parameters corresponding to the second node. The method can also include storing the indication of the request in a report list, and transmitting, via the virtual link, a neighbor advertisement (NA) message to the first node in response to the NS message, wherein the NA message comprises the one or more communication parameters corresponding to the second node.

In an example, a method is described that comprises forming an MNP uniquely associated with the client aircraft. The method comprises embedding the MNP in a source address. The method additionally comprises sending a router solicitation message to a fixed router in a ground service network, wherein the router solicitation message comprises the source address. The method also comprises receiving, by the mobile router of the client aircraft from the fixed router in the ground service network, a router advertisement message, wherein the router advertisement message comprises configuration information for subsequent communications between the mobile router of the client aircraft and the fixed router. The method still further comprises determining, by the mobile router of the client aircraft, based on receiving the router advertisement message, that (i) the MNP of the client aircraft has been delegated and (ii) the client aircraft has permission to communicate over the ground service network.

Systems and methods for automatically registering a mobile router in a service network

An underwater communications system includes a network communication interface, one or more computer processors, and a memory containing computer program code that, when executed by operation of the one or more computer processors, performs an operation. The operation includes storing a plurality of data packets to be transmitted to a destination device, determining that data communications over the network communication interface have become available for a first network node, and determining that the first network node has a valid security credential. Additionally, the operation includes, upon determining that the first network node has the valid security credential, transmitting the stored plurality of data packets over the network communication interface to the first network node. The first network node is configured to employ store-carry-and-forward data messaging techniques to transmit the plurality of data packets towards the destination device.

An underwater communications system includes a network communication interface, one or more computer processors, and a memory containing computer program code that, when executed by operation of the one or more computer processors, performs an operation. The operation includes storing a plurality of data packets to be transmitted to a destination device, determining that data communications over the network communication interface have become available for a first network node, and determining that the first network node has a valid security credential that has not been revoked by an access granting authority. Additionally, the operation includes, upon determining that the first network node has the valid security credential, transmitting the stored plurality of data packets over the network communication interface to the first network node. The first network node is configured to employ store-carry-and-forward data messaging techniques to transmit the plurality of data packets towards the destination device.

A system is provided for secure data transmission. The system stores a public master key, private decryption key and secure messaging module for securely transmitting and receiving a digital model data file for transmission via a work order message. For transmitting and receiving the work order message, the system generate public encryption keys using a key generation algorithm in which each of the public encryption keys are unique to a designated message recipient and generated using an input including the public master key, a validity period, and an identifier of the designated message recipient. The system may also store a revocation list that includes identifiers of message recipients that have revoked access to the public master key or private decryption key, and based thereon determine whether or not to encrypt and transmit the work order message, or receive and decrypt the work order message.

Secured data transmission using identity-based cryptography

A method for managing network traffic is described which includes receiving a traffic engineering specification at a Server from a Client, receiving a communication at the Server, a destination of the communication being the Client, and sending the communication from the Server to the Client via a tunnel virtual interface configured over one or more of Internet service provider (ISP) connections associated with the Client based on the traffic engineering specification, the tunnel virtual interface being a point of connection to a tunnel virtual network link.
