Abstract
A method for automation and control of a wireless device in a WiFi environment. The method includes a wireless mobile device configured with a soft access point (softAP) transmitting probe requests to home automation devices and traditional stationary access points. The wireless mobile device periodically wakes up to scan for other services, sends a probe request, authenticates the received probe response from the another device and receives control information via the received probe response.
Claims13
A method for automation and control of wireless devices comprising:
- receiving in a device an encryption key and authentication table from a mobile device, wherein said device uses this key to subsequently encrypt both control and authentication information in a Service Set Identifier (SSID);
- and
- said device using the encryption key and authentication table in accepting only encrypted and authenticated SSID information from other devices.
A method for automation and control of wireless devices comprising:
- receiving in a device an encryption key and authentication table from a mobile device, wherein said device uses this key to subsequently encrypt both control and authentication information in the Service Set Identifier (SSID);
- said device using key authentication table in accepting only encrypted and authenticated SSID information from other devices;
- and
- wherein said device translates Smart Energy Protocol communication to and from said encoded SSID.
A method for automation and control of wireless devices comprising:
- receiving in a device an encryption key and authentication table from a mobile device, wherein said device uses this key to subsequently encrypt both control and authentication information in the Service Set Identifier (SSID);
- said device using the encryption key and authentication table in accepting only encrypted and authenticated SSID information from other devices;
- and
- wherein said device translates Smart Energy Protocol communication to and from said encrypted SSID information.
A wireless device comprising:
- a receiver for receiving an encryption key and authentication table from a mobile device, wherein said key is used to subsequently encrypt both control and authentication information in the Service Set Identifier (SSID);
- and
- logic for accepting only encrypted and authenticated SSID information from other devices by using the received encryption key and authentication table.
A wireless device comprising:
- a receiver for receiving an encryption key and authentication table, wherein said key is used to subsequently encrypt both control and authentication information in the Service Set Identifier (SSID);
- logic for accepting only encrypted and authenticated SSID information from another device after said encryption key and authentication table are received;
- and
- wherein said wireless device communicates with said another device using Smart Energy Protocol communication after encrypted and authenticated SSID information provided by said another device is accepted by said wireless device.
