The security of the mobile environment is the focus of this research proposal. This proposed research program will consider the security of the mobile cellular network and location-aware services of the mobile environment. The research will consider contemporary LTE (Long Term Evolution) and future LTE-Advanced networks as well as earlier 2G and 3G networks as all current operational networks evolved to run these technologies side-by-side and are expected to do for some time. On the mobile cellular network side, the proposal will investigate the relationship between the complexity of the mobile network and security issues. Investigating ways to reduce the mobile network complexity could help reduce its susceptibility to a number of attacks that exploit this complexity. The second investigated aspect is proposing evasion-resistant geolocation techniques to enhance the security of certain location-based services. Several attacks in mobile networks and on the Internet succeed because of the attackers' ability to hide their location. While most mobile devices are equipped with location capabilities, the information obtained from a service about a certain device location cannot be trusted since the device could send false location information to the service. This proposal will look into ways beyond relying on a device's IP address or the information supplied by the device to a service to verify if there is an attempt to evade the geolocation required by certain services.
