Security in mobile environments

移动环境的安全性是本研究计划的重点。该研究计划将考虑移动蜂窝网络的安全性和移动环境中的位置感知服务。该研究将考虑当前的LTE（长期演进）和未来的LTE- advanced网络，以及早期的2G和3G网络，因为所有当前的运营网络都在发展，以并行运行这些技术，并且预计将在一段时间内这样做。在移动蜂窝网络方面，该提案将研究移动网络的复杂性与安全问题之间的关系。研究降低移动网络复杂性的方法可以帮助降低其对利用这种复杂性的许多攻击的易感性。第二个研究方面是提出抗规避的地理定位技术，以增强某些基于位置的服务的安全性。移动网络和互联网上的几次攻击之所以成功，是因为攻击者有能力隐藏自己的位置。虽然大多数移动设备都配备了定位功能，但由于设备可能会向服务发送错误的位置信息，因此从服务获得的关于某个设备位置的信息是不可信的。该提案将研究除了依赖设备的IP地址或设备提供给服务的信息之外的方法，以验证是否存在企图逃避某些服务所需的地理位置。

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.
