A method includes receiving, at a network node, a device-to-device D2D discovery request from a first device and sending a D2D discovery response from the network node to the first device. The D2D discovery response includes information associated with a second device that is available to establish a D2D connection with the first device. The network node may perform inquiries regarding D2D connection permission from both devices. If D2D connection is permitted by both devices, the network node may facilitate the D2D scanning by sending each device's scanning information to the other device via a non-D2D link. In parallel to D2D scanning, the network node may speed up D2D link setup by distributing, via non-D2D links, link setup information to each device, where the link setup information may include device credential(s), IP address allocation(s), and / or group owner assignment.

A social messaging hub provides communication services for a data enabled device having Internet network access capabilities. The social messaging hub communicates with the data enabled device over the Internet or cellular data networks, and interfaces with a message infrastructure including mobile carriers, message aggregators, message exchanges and various specialized social messaging services to enable bi-directional messaging communication. The user is given a registered phone number and unique IP addressable identification which serve as a source and destination identifier of the associated data enabled device. Messages may originate in or be delivered to other users' mobile telephones or in similarly equipped and provisioned IP data enabled devices. An application operating on the IP enabled device determines in conjunction with the social messaging hub a mode of transmission as a function of parameters including device location and destination of a message.

This invention provides improved security of the McEliece Public Key encryption system adding features which make full use of random number generation for given message and cryptogram parameters. Different embodiments of the invention are described which enable the level of security to be traded-off against cryptogram size and complexity. Message vectors are encoded with a scrambled generator matrix, using matrix multiplication to form codeword vectors. Shortened corrupted codewords are generated by corrupting each codeword vector and omitting a predefined number of bits, whereby a cryptogram is formed from the shortened corrupted codewords. Measures are included to defeat attacks based on information set decoding. A number of different applications are given.

It is proposed a device and method for finding nilcatenations, and proposes nilcatenation detection techniques, which can be applied to blockchains, and even constitute a proof of useful work, as the periodic removal of nilcatenations keeps a ledger size as small as possible. Banks and blockchains need to keep track of an ever-increasing list of transactions between the accounts owned by their users. However, as time goes by, many of these transactions can be safely “forgotten”, in the sense that purging a set of transactions that compensate each other does not impact the network's semantic meaning i.e. the vector Bt of amounts representing the balances of users at a given point in time t. Nilcatenation refers to a collection of past transaction vectors having no effect on Bt. Removing these transactions yields a smaller, but equivalent set of transactions.

Different embodiments of the invention are described which enable the level of security to be traded-off against cryptogram size and complexity. A number of different applications are given.
