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.

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, using this invention the encrypted message (i.e. the cryptogram) is a truly random function, not a pseudo random function of the message so that even with the same message and the same public key, a different, unpredictable cryptogram is produced each time. With the knowledge of the private key, the random function may be determined from the cryptogram and the message decrypted. 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.

The invention discloses a method, a device and a system for network prepayment, which are used for solving the problem that too many interactions of corrected authorization messages exist between an access server and an authentification, authorization and charging server and occupy too many resources. The method mainly comprises the following step: the authentification, authorization and chargingserver responds an authentification response message indicating the maximum user on-line time length or available time length to the access server according to a credit control response primary message sent by an on-line charging system, and in each subsequent charging time length, only charges for the previous charging time length and pre-distributes the work for the next available time length. The method can reduce the message transmission between the access server and the authentification, authorization and charging server, thereby saving the resources.

A method for informing that the network supports the mobile Internet Protocol (IP) enhancement capability includes the network sending a message indicating the mobile IP enhancement capability of the network to a mobile station (MS). If the MS supports the mobile IP enhancement capability, the MS requests the enhanced mobile IP service according to the mobile IP enhancement specifications. If the MS does not support the mobile IP enhancement capability, the MS requests the mobile IP service according to the specifications which do not support mobile IP enhancement. The packet data access gateway may be a packet data serving node (PDSN) or a controlling access point (CAP) in a Code Division Multiple Access (CDMA) evolving network. Therefore, the method provided by the present disclosure enables the MS to learn the mobile IP enhancement capability of the network without having to resending requests, thus avoiding the waste of air interface resources.

The invention relates to a lamp control system communication protocol encryption method in the field of computers. The method adopts a method of dynamically generating secret key encryption at a receiving end and a sending end. The sending end extracts a secret key parameter I dynamically generated by sending end data frame information to ensure that the sending secret keys are different each time. A private password by a user is used as a key parameter II to participate in the generation of the key, so that security is higher. A key parameter III transmitted next time is contained in the dataframe transmitted this time, and the receiving end is informed to update the key parameter III. In the first transmission, the key parameter III generates a key by adopting a preset initial value, and after the sending and receiving processes are completed each time, the key parameter III is updated at the receiving end and the transmitting end. According to the invention, messages specially distributed by keys can be reduced. In addition, the private password set by each user is used as the key parameter to participate in the generation of the key, so that the security can be improved.
