Abstract
A secure indoor positioning device, system and method. A mobile electronic device is detected entering into proximity of a stationary electronic device. In response, a plurality of secure session parameters is negotiated via two-way wireless communication between the stationary electronic device and the mobile electronic device. One or more of the negotiated plurality of secure session parameters is communicated to one or more other stationary electronic devices. At one or more of the plurality of stationary electronic devices, secure messages broadcasted by the mobile electronic device are received. These messages are decrypted or authenticated using one or more of the negotiated secure session parameters and are used to determine a position of the mobile electronic device.
