Abstract
A method and system for enabling devices to join secure networks without requiring the devices to be aware of any particular security credential delivery mechanism or to implement multiple security credential delivery mechanisms.
Claims31
A method, performed by an information processing device including a processor, of adding a target device to a secure network, the method comprising:
- establishing, using the processor, a communication link between a client device already a member of the secure network and the target device to be added to the secure network,
- wherein, before the communication link is established, the target device is separate from the secure network and unauthenticated on the secure network;
- obtaining, using the processor, security credential information in place of the target device from the secure network at the client device, in response to the establishing of the communication link with the target device,
- wherein, the security credential information is obtained in place of the target device via the client device already a member of the secure network;
- impersonating the target device and participating in the process of obtaining security credential information on behalf of the target device;
- and
- transferring, using the processor, the obtained security credential information from the client device to the target device,
- wherein the target device is added to the secure network using the obtained security credential information, and
- wherein the target device to be added to the secure network is security credential delivery mechanism independent or supports a security credential delivery mechanism different from a security credential delivery mechanism being used by the secure network.
6 more elements
A system for adding a device to a secure network, the system comprising:
- a client device, wherein the client device is a member of the secure network;
- at least one target device, wherein the target device is separate from the secure network and unauthenticated on the secure network;
- the client device comprising:
- a communication unit that establishes a communication link between the client device and the at least one target device;
- an obtaining unit that obtains security credential information in place of the target device from the secure network, in response to the establishing of the communication link with the target device,
- wherein, the security credential information is obtained in place of the target device via the client device already a member of the secure network,
- the client device impersonating the target device and participating in the process of obtaining security credential information on behalf of the target device;
- a transfer unit that transfers the obtained security credential information to the at least one target device;
- the at least one target device comprising:
- a communication unit that provides identification information of the target device;
- and
- a receiving unit that receives security credential information from the client device,
- wherein the at least one target device is added to the secure network using the obtained security credential information, and
- wherein the at least one target device is security credential delivery mechanism independent or supports a security credential delivery mechanism different from a security credential delivery mechanism being used by the secure network.
