Various other aspects are contemplated.

A method including communicating, by a first device in communication with a second device in a mesh network, meshnet data with the second device based at least in part on utilizing a meshnet local port dedicated for communicating the meshnet data; and transmitting, by the first device to a control infrastructure device, a binding request based at least in part on utilizing the meshnet local port, the binding request requesting the control infrastructure to determine a currently allocated public port associated with the first device. Various other aspects are contemplated.

Some embodiments provide a method that collects metrics for one or more paths of a first tunnel implementing a first security association (SA) and for one or more paths of a second tunnel implementing a second SA. The method selects a path based on the collected metrics of the paths of the first and second tunnels. When the selected path belongs to the first tunnel, the method encrypts data transmitted as encrypted payload of the first SA and transmits the encrypted payload in the first tunnel. When the selected path belongs to the second tunnel, the method encrypts data to be transmitted as encrypted payload of the second SA and transmits the encrypted payload in the second tunnel.

Techniques are disclosed relating to securely authenticating communicating devices. In various embodiments, a computing device receives, via a network connection with a network, a first certificate for a first public key pair of the computing device. The computing device provides the first certificate to an offline accessory device and receives a second certificate for a second public key pair maintained by the offline accessory device. The computing device performs a verification of the second certificate and, responsive to the verification being successful, interacts with the offline accessory device. In some embodiments, prior to providing the first certificate, the computing device determines an ordering in which the first and second certificates are to be exchanged by the first computing device and the offline accessory device, and the first certificate is provided to the offline accessory device in accordance with the determined ordering.

A method performed by a device for identifying a network node within a network to which data will be replicated is disclosed. The method comprises encrypting a session key according to an attribute-based encryption scheme; broadcasting the encrypted session key within the network; receiving at least one message encrypted using the session key from at least one network node within the network; and selecting a network node from the at least one network node to which data will be replicated. A further method, a device and a non-transitory machine-readable medium are also disclosed.

Broadly speaking, the present technique provides methods, apparatuses and systems for performing a TLS/DTLS handshake process between machines in a manner that reduces the amount of data sent during the handshake process.

A key management apparatus receives a key request including a first device identification information and a second device identification information, encrypts a common key using the first device identification information to generate a first encrypted common key, encrypts the common key using the second device identification information to generate a second encrypted common key, and transmits a key response including the first encrypted common key and the second encrypted common key. A first device receives the key response, decrypts the first encrypted common key using the first device identification information to obtain the common key, and transmits the second encrypted common key. A second device receives the second encrypted common key and decrypts the second encrypted common key using the second device identification information to obtain the common key.

An example client device includes a processor configured construct a key to be used to encrypt or decrypt data of a communication session between the client device and a server device, partition the key into a plurality of key partitions, send data representative of the key and a location of the client device to the server device, send data representative of each of the plurality of key partitions to a respective key verification server device of a plurality of key verification server devices, and after receiving an indication from the server device that the key has been verified using data representative of the key, the location of the client device, and the plurality of key partitions, encrypt or decrypt data exchanged with the server device using the key.
