Abstract
Before establishing a connection between a first and a second devices, the first device determines whether a third device is a trusted or untrusted device. If it is a trusted device, the first device receives from the third device a public key and information indicating the public key of the second device; and, uses the public key by combining its own private key and the public key of the second device to generate a shared secret, and using the shared secret to communicate to the second device. Otherwise, the first device refrains from communications with the third device. Also, the second device combines its private key with the public key of the first device received from the trusted third device to generate the same shared secret, and uses the shared secret to provision the first device to access a secured wireless network provided by the second device.
