The present invention relates to an intelligent gardening system, for monitoring and controlling gardening apparatuses in a gardening area, including: multiple sensors that collect environmental information of the gardening area; one or more gardening apparatuses that perform gardening work according to a control instruction; and a control center that generates the control instruction based on the environmental information; wherein the sensors, the gardening apparatuses and the control center communicate with each other to form an Internet of Things.

It is provided an information sharing system, comprising a server, and an in-vehicle system. The server includes: a first storage part; a first key generation part configured to generate a first private key and a first public key, if keys can be exchanged with the in-vehicle system; and a signature generation part configured to generate a signature value of the first public key using a server private key. The in-vehicle system includes: a second storage part configured to store a public key certificate including a server public key; a signature verification part configured to verify the first public key and a signature value received from the server, using a public key certificate; and a second key generation part configured to generate a second private key and a second public key, if a combination of the first public key and the signature value is correct as a result of the verification.

Connectionless data transfer is disclosed. Authentication of a device and network node may be performed when data is sent from the device to an application server of an application service provider via a selected network. The transfer of data may take place in an absence of an existing device context between the network node interacting with the device and the core network through which the data travels. State management overhead and signaling overhead may be reduced by use of the exemplary aspects disclosed herein. For example, the device does not need to perform an authentication and key agreement (AKA) procedure to transfer the data and an existing (or pre-existing) device context need not be maintained at the core network.

Technologies for a distributed Internet of Things (IoT) system are disclosed. Several IoT devices may form a peer-to-peer network without requiring a central server. Information may be stored in a distributed manner in the distributed IoT system, allowing for storing information without transmitting it to a remote server, which may be costly and introduce security or privacy risks. Each IoT device of the distributed IoT system includes a machine learning algorithm that is capable of uncovering patterns in the input of the distributed IoT system, such as a pattern of user inputs in certain situations, and the distributed IoT system may adaptively anticipate a user's intentions.

An in-flight entertainment and communications (IFEC) system is configured to interconnect an avionics data bus to a local area network. An avionics interface is connectable to the avionics data bus, and receptive to avionics data transmitted on the avionics data bus by one or more avionics nodes over a predetermined protocol. A local network interface establishes the local area network, and portable electronic devices may be connectable to the local network interface over the local area network to establish a data communications link thereon. A data processor is connected to the avionics interface and the local network interface, and relays the avionics data from the avionics interface to the local network interface for transmission to the one or more portable electronics devices. This transmission is according to the predetermined protocol over the data communications link established on the local area network.

Systems, methods, and instrumentalities are disclosed that provide for a gateway outside of a network domain to provide services to a plurality of devices. For example, the gateway may act as a management entity or as a proxy for the network domain. As a management entity, the gateway may perform a security function relating to each of the plurality of devices. The gateway may perform the security function without the network domain participating or having knowledge of the particular devices. As a proxy for the network, the gateway may receive a command from the network domain to perform a security function relating to each of a plurality of devices. The network may know the identity of each of the plurality of devices. The gateway may perform the security function for each of the plurality of devices and aggregate related information before sending the information to the network domain.

Embodiments of the present invention include a method for providing a secure domain name system (DNS) for machine to machine communications. In one embodiment, the method includes storing policy information for machine to machine communications in a global DNS registry database server. The method further includes communicating the policy information for machine to machine communications from the global DNS registry database server to a machine DNS registry server located in an Internet service provider (ISP) network, wherein a control signaling gateway located in the ISP network is configured to utilize the policy information for machine to machine communications to allow only registered controllers associated with a machine to communicate with the machine.

A first network node of a first frequency layer, acquires (201) information on services that are offered by a second network node at a second, different frequency layer. The second network node is within the coverage area of the first network node. The first network node broadcasts (202) a service advertisement message to at least one terminal device (UE) for advertising the services offered by the second network node at the second frequency layer.

A method for managing data of devices using one or more computing entities includes encrypting, by one or more encrypting entities, the data based on encryption policies using encryption keys; storing the encrypted data as ciphertext at a storing entity; requesting decryption keys to decrypt the stored ciphertext by one or more clients; computing restricted decryption keys based on access right policies for the requesting clients by a security management entity; and providing the generated decryption keys to the requesting clients for decrypting the stored ciphertext.

A method and device for data transmission in a wireless communication network are provided. The method includes: in data reported by multiple transmitter nodes and received by a receiver node, when a statistical result of data reported by K transmitter nodes satisfies one of preset conditions, selecting one transmitter node from the K transmitter nodes, herein K is an integer greater than 1; the receiver node receiving data subsequently transmitted by the selected transmitter node; and the receiver node notifying unselected K−1 transmitter nodes of optimization information and the data subsequently transmitted by the selected transmitter node, herein the optimization information includes a basis for a transmitter node to determine whether to transmit subsequent data.
