The latest advances in the mobile communication industry have led to the integration and intercommunication of existing and future networks together with radio access technologies. Mobile communications have been evolving from a static and rigid system to a highly dynamic environment.One of the key elements to successfully achieve the benefits of having a highly dynamic environment is the availability of Software Defined Radio Technology and Software Defined Radio Mobile Devices (SDR-MDs) with reconfigurable protocol stacks and their equivalent on the network side.Despite several advantages there are still issues to be discussed regarding security. To address the security concerns and greatly enhance the overall security of SDR-MDs a fraud-prevention framework is proposed.The contributions presented in this book are security monitoring against malicious attacks and viruses, protection of sensitive information through the use of protected storage, creation and protection of an identity for the system, techniques to update R-CFGs in a secure and efficient manner and, the main contribution, to establish an anti-cloning scheme that makes the device itself aware of cloning.
