    • A secure wireless communication link (pairing) between two devices can be established using cleartext wireless transmissions between devices not joined to a network (“probes”). One device can broadcast a first probe indicating that it is seeking to establish a pairing. The other device can respond with a second probe, and the two devices can establish a shared secret, e.g., by exchanging further information using additional probes. Thereafter, either device can send a message to the other by encrypting the message using a cryptographic key derived from the shared secret; encrypted messages can also be sent within probes. The receiving device can extract an encrypted message from a probe and decrypt it using the cryptographic key. The encrypted message can include credentials usable by the receiving device to join a wireless network.
    • 可以使用未连接到网络的设备(“探针”)之间的明文无线传输来建立两个设备之间的安全无线通信链路(配对)。 一个设备可以广播指示其正在寻求建立配对的第一探测器。 另一个设备可以用第二探测器进行响应,并且这两个设备可以建立共享的秘密,例如通过使用附加探测器交换进一步的信息。 此后,任一设备都可以使用从共享密钥导出的加密密钥对消息进行加密来发送消息; 加密消息也可以在探测器内发送。 接收设备可以从探测器中提取加密消息,并使用加密密钥对其进行解密。 加密的消息可以包括接收设备可用于加入无线网络的凭据。
