    摘要: Scheme and apparatus (10) for distinguishing services offered by a service-providing device in adjacency of the apparatus (10) from services offered by a service-providing device not being in the apparatus' adjacency. All devices—including the apparatus—are part of a wireless local network. The apparatus (10) maintains a record with information about services and associated identifiers as well as a list of identifiers about the service-providing devices. The associated identifiers and the list of identifiers are compared to determine an associated service as being in adjacency of the apparatus if it is rendered by a service-providing device being listed in the list of identifiers. An associated service is determined as not being in adjacency of the apparatus if it is rendered by a service-providing device not being listed in the list of identifiers. The apparatus (10) comprises a network interface (25) for wireless communication with the service-providing devices, and a service discovery module (11) which maintains the record with information services and associated identifiers.

    摘要: Methods, system and apparatus are provided for advertising service offerings in a communication system. An example embodiment comprises at least one device. A first device broadcasts a message of a first type, chooses a value for a time limit and listens for a message sent by a second device. If no message has been received before time limit, elapse, it again broadcasts a message of a first type. Otherwise, the message received from said second device is analyzed and if said message includes valid information about said first device chooses a value for the time limit. However, if said message received does not include valid service description about said first device, a message of a second type is broadcast. This reduces useless broadcast of a complete service list. Broadcast may be initiated more often and, service discovery for new devices coming into proximity takes less time.

    摘要: There is provided a method and a system for documenting a transfer of authority of control for a container from a first entity of a transportation chain to a second entity of the transportation chain. The first entity transfers an electronic container control certificate to an electronic seal of the respective container, which electronic container control certificate comprises a cryptographic key associated to the second entity, and which container control certificate is digitally signed by the first entity. The container control certificate is stored in a log of the electronic seal.

    摘要: A WPAN system for establishing communication between a control station of a cargo vessel and a plurality of containers that are loaded onto the vessel is provided that comprises a base station configured to establish and manage a pre-configured WPAN having a hybrid tree-mesh network topology and a plurality of electronic tracking devices each being provided with a WPAN-enabled radio receiver/transmitter and routing capabilities. The base station is configured to communicate with the control station through a local area network on the vessel. Each tracking device is configured to be joined to a respective container of the plurality of containers and to connect to the WPAN upon being activated. The base station is configured to intermittently perform a network scan to locate each tracking device that is connected to the WPAN and dynamically reconfigure the network topology to include each tracking device connected to the WPAN to maintain mutual communication with each connected tracking device using the routing capabilities of the tracking devices.

    摘要: In one embodiment, a computer-implemented method for authentication by kinematic pattern match is provided. The computer implemented method prompts a user for a kinematic input, receives an element of a kinematic pattern to form a set of received elements, and determines whether there are additional elements of the kinematic pattern. Responsive to a determination that there are no additional elements of the kinematic pattern, forms a kinematic pattern from the set of received elements and computes a signature from the set of received elements. The computer implemented method further determines whether the signature matches a predetermined value, and responsive to a determination that the signature matches a predetermined value, sends an authentication signal.
