In the last years mobile smartphones have become an extension of everyday life, by proving ubiquitous access to different services, such as banking, social network, investing, and communications. Therefore, security is one of the most important aspects to consider when design and develop an mobile System on Chip, like Qualcomm Snapdragon. This document is the final report about the internship performed at Qualcomm, as member of SVE team (System Validation and Emulation). The main purpose of this thesis is to show and understand how is performed the validation phase for a security component, by focusing on the implementation of drivers and test cases for the Memory Protection Units.
