The superior reconfigurability of software defined radio mobile devices has made it the most promising technology on the wireless network and in the communication industry. Despite several advantages, there are still a lot to discuss regarding security, for instance, the radio configuration data download, storage and installation, user's privacy, and cloning. The objective of this paper is to present a fraud-prevention framework for software defined radio mobile devices that enhances overall security through the use of new pieces of hardware, modules, and protocols. The framework offers security monitoring against malicious attacks and viruses, protects sensitive information, creates and protects an identity for the system, employs a secure protocol for radio configuration download, and finally, establishes an anticloning scheme, which besides guaranteeing that no units can be cloned over the air, also elevates the level of difficulty to clone units if the attacker has physical access to the mobile device. Even if cloned units exist, the anticloning scheme is able to identify and deny services to those units. Preliminary experiments and proofs that analyze the correctness of the fraud-prevention framework are also presented.
