Abstract: A Personal Area Network Security Domain (PSD) is formed between devices (142, 150, 152, 154 and 156). The PSD allows the sharing of data and/or resources between the devices within the PSD. The devices within the PSD are located remotely from one another. For example, communication between device (150 and 156) will be performed via mobile or cellular telephone network (120), the Internet (140) and mobile or cellular telephone network (126). Each network (120, 126) is provided with a PSD Hub, which enables an IPsec secure connection between the devices (150 and 156) to be established.

Abstract: A Personal Area Network Security Domain (PSD) (50) is formed between PDA (52), mobile terminal (54), PC (56) and printer (58). The PSD (50) allows the sharing of resources between the devices within the PSD. If the devices within the PSD (50) are located remotely from one another, communication between those devices will be performed via mobile or cellular telephone network (66) and the Internet (68). For each set or association of similarly located devices within the PSD (50), one of those devices will be a gateway device. The gateway device is a device that is configured to communicate with an external communications medium (mobile network (66) or the Internet (68)). Data transmissions to other devices within the PSD are channelled through the relevant gateway. In another embodiment resources are shared between the two separate PSDs (of which may or may not be remotely located with respect to one another) by means of data exchanges between the respective gateway devices of the two PSDs.

Abstract: A network (11) including a plurality of devices (A . . . F), each device being capable of wireless communication with the other devices of the network. One of the devices (C) includes administration means for allowing selected devices (A, B, C) to be associated within a domain (13) by providing each device (A, B, C) with identification data, the identification data of each device being interpretable by each other device within the domain, communication only being allowed between devices within the domain having such identification data. Controlled resource sharing between devices is permitted.
