摘要： Disclosed is a method for establishing a wireless link key between a remote device and a group device. In the method, the remote device obtains a group identifier from the group device, and determines whether the group device is associated with a group having a trust association with the remote device. When the group device is determined to be associated with a group having an established trust association with the remote device, the remote device forwards a link setup request to the group device for virtually pairing with the group device using the trust association to establish the wireless link key. When the group device is determined not to be associated with a group having an established trust association with the remote device, the remote device forwards a pairing request to the group device for pairing with the group device to establish the wireless link key.

摘要： Disclosed is a method for address privacy protection for a first wireless device sharing a privacy key with a second wireless device. In the method, a first resolution tag is generated at the first wireless device using a pseudo-random function with the seed value and the privacy key as input arguments. The privacy key is only known to the first and second wireless devices. A privacy address is generated for the first wireless device based on the seed value and the first resolution tag. A packet is transmitted from the first wireless device to the second wireless device. The packet includes the privacy address and the first resolution tag.

摘要： One feature provides a method for a client node to establish a session key with a group node by obtaining an epoch identity value associated with a current epoch, wherein obtaining the epoch identity value includes one of computing the epoch identity value based on a node real time or negotiating the epoch identity value with the group node, computing a restricted key using a shared secret key, the epoch identity value, and a group node identity associated with the group node, and executing a session key establishment protocol with the group node to derive the session key using the restricted key as a master key in the session key establishment protocol. The session key may be established between the group node and the client node even though communications between the group node and the central node is only intermittently available during the current epoch.

摘要： Disclosed is a method for virtual pairing of a first peer device with a second peer device. In the method, a nonce is generated at the first peer device for use in virtually pairing the first and second peer devices to establish a first-type wireless connection. The nonce is forwarded from the first peer device to the second peer device over an already established second-type wireless connection between the first and second peer devices. At least one new key is generated from the nonce and a shared key for the already established second-type wireless connection. The first peer device is virtually paired with the second peer device using the at least one new key to establish the first-type wireless connection between the first and second peer devices.
