 In this implementation, similar recordings of ambient audio from mobile devices in proximity are utilised for the generation of a secure key.
 An attacker that is farther away is not able to guess the same key with a recording of her own since the features in the ambient audio differ with location.
+However, the robustness of the generated key is dependent on properties of ambient audio.
+In previous studies, we experienced best pairing characteristics when devices are in an environment with a single loud audio source.
+When environmental noise is, however, more ubiquitous and noisy, it is easier for an attacker to generate a key that is similar to that of the legitimate communication partners.

+In this project we will develop a mechanism to adapt the parameter of the underlying approach to generate secure to changing environmental parameters.
-Indoor positioning still remains a challenging task since GPS does not work indoors and reliable.

-Furthermore, ubiquitously deployed alternatives are not available.
-Recenty, localisation techniques based on radio frequency measurements have been proposed.
-In this project, the student(s) will design and implement an indoor localisation system based on RF-signal strength fluctuation.
-We will provide USRP software defined radio devices and further required hardware equipment to design an accurate RF-based indoor localisation system.
-In the frame of the 2014 IPSN Indoor Localisation Competition [http://ipsn.acm.org/2014/content/pdf/IndoorLocation-CFC.pdf] the designed system can be tested under realistic conditions.
-A participation is highly appreciated and will be supported.
