The rapid diffusion of mobile communication technology and smart phone devices has raised the concerns about the security problems of mobile phone accessories. Despite a few effort has been made in this aspect, there are still some deficiencies such as poor compatibility and limited application scope. This article presents a trusted mobile phone accessory identification scheme. Our method uses physically unclonable function (PUF) as hardware security primitives which are embedded in mobile phone accessories to generate digital signatures, so that they can be applied to identify authorized mobile phone accessories. We finally implement the proposed scheme on a field programmable gate array (FPGA) platform. Experimental results show that our solution can effectively identify trusted mobile phone accessories.
