Abstract: During a security technique, an electronic device determines a name by a applying a function to a shared secret, which is shared between a user and another user. This name is advertised in a network. After discovery by another electronic device (which is associated with the other user), the electronic device generates a first encrypted message from an unencrypted message using a cryptographic key. The electronic device provides the first encrypted message to the other electronic device, and receives a second encrypted message from the other electronic device. Using the cryptographic key, the electronic device decrypts the second encrypted message. Moreover, the electronic device receives confirmation that the other electronic device was able to decrypt the first encrypted message, thereby authenticating that the secure connection has been established.

Abstract: Methods and apparatus are provided for detecting interference between spectrally distinct wireless communication networks. A first base station in a first network communicates with a first mobile device at a first frequency, and a second base station communicates at a second frequency with a second mobile device geographically co-located with the first mobile device. The power level of an interfering signal received at the first base station from the second mobile device may be estimated by sharing information between the two networks through an interoperability gateway. The path loss of a reference signal transmitted from the first mobile device to its base station is communicated to the gateway, along with a parameter associated with the transmit power level of the interfering signal. Based on this parameter and the reference signal path loss, the received power level of the interfering signal may be inferred.
