摘要： A secure wireless communication system has a communication device acting as a service seeker (210) and a further communication device acting as a service provider (220) according to a security protocol defining link layer security according to a security mechanism. The service provider enables a first service requiring a link layer security according to a first security mechanism. The devices establish a first secure link connection 5 (241) to engage the first service. The service provider determines that a further service requires a link layer security according to a second security mechanism different from the first security mechanism. The devices now establish a second secure link connection (242) on the link layer according to the second security mechanism while the first secure link connection remains active to engage the further service via the second secure link connection, 10 while blocking the service seeker from accessing the further service until the second secure link connection has been established.

摘要： A first device (110) for distance measurement via wireless communication (130) uses a ranging protocol for determining a distance (140) to a second device (120) via a round trip time measurement, wherein first time data represents the round trip time and second time data represents a response time between receiving a request and sending a corresponding acknowledge. The second device receives the round trip time and determines the distance. The first device determines third time data by subtracting from the first time data a calculated travelling time of the messages between the first device and the second device based on the determined distance, and determines identifier data indicative of hardware and/or software present in the second device. The device then obtains, from a database based on the identifier data, a reference interval value, and verifies whether the determined distance is reliable by comparing the third time data to the reference interval value.

摘要： A wireless device (S) includes a radio (R) for communicating via a wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. The wireless device is configured to operate in (i) a first mode in which the wireless device transmits messages (N0, . . . , Nn) via the radio each including an IPv6 packet header and an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame, and (ii) a second mode in which the wireless device transmits messages (M0, . . . , Mn) via the radio each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. A relay device (T) comprises a radio for communicating via the wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. In one power-saving aspect, the relay device is configured to perform a header insertion service (I) in which the relay device receives messages (M0, . . . , Mn) via its radio from the wireless device (S), each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. The header insertion service inserts header information (A′) into the messages (M0, Mn) received from the wireless device (S) and retransmits the messages with complete headers as messages (M0′, . . . , Mn′). In another power-saving aspect, the relay device additionally or alternatively applies an acknowledgement detection criterion to filter out acknowledgements received from the server, and forwards the filtered out acknowledgements to the wireless device (S) via the radio at a reduced rate.

摘要： A cellular communication system supports network slicing and has a network relay function (140) for managing the indirect connections. A mobile device (110) may send a request message to a relay device (120), the request message including a slice to access. A response message indicates available slice(s) and relay device(s). The device selects a slice and/or relay device in dependence of the response message. The relay device receives the request message and sends a transfer request message to the cellular communication system indicating a request to transfer data via an indirect connection and including the requested slice, and sends the response message. The network relay function receives the transfer request message, obtains relay capability data regarding relay device(s) capable of data transfer for available slice(s) in dependence of the requested slice; and sends a transfer response message including network relay information indicating the available relay device(s) that can serve as relay device for indirect communication with the requested network slice.

摘要： A device (110) arranged for wireless communication (130) according to a communication protocol has a processor (112) to execute a connection sequence according to a discovery protocol. The connection sequence comprises determining a current cluster identity and a current discovery window timing used by the device. Next, at least one other device (120,120′) within wireless range is detected, while further determining a detected cluster identity and a detected discovery window timing of the detected other device. Then it is detected whether the detected device is operating in a different cluster than the device by comparing the current cluster identity with the detected cluster identity or comparing the current discovery window timing with the detected discovery window timing. Finally, upon detecting said different cluster, a security process is executed, which may warn the user or abort the connection sequence. Thereby, a malicious device trying to manipulate the connection sequence is detected.
