Measuring integrity on mobile phone systems

摘要: Mobile phone security is a relatively new field that gathering momentum in the wake of rapid advancements system technology. phones are now becoming sophisticated smart provide services beyond basic telephony, such as supporting third-party applications. Such applications may be security-critical, mobile banking, or untrusted applications, downloaded games. Our goal to protect integrity critical from potentially functionality, but we find existing mandatory access control approaches too complex and do not formal guarantees. In this work, leverage simplicity inherent environments develop compact SELinux policy can used justify using Policy Reduced Integrity Measurement Architecture (PRIMA) approach. We show resultant enables systems proven secure remote parties, desired functionality for installing running trusted programs, over 90% smaller size. envision approach an outline how build high systems.
