A Security Hygienic Smart Charger for Mobile Devices
نویسنده
چکیده
Measuring and attesting to the operational integrity and security posture of a mobile device is challenging. Today, smart phones and tablet computers lack a number of traditional security features that have emerged for commodity laptops and desktops. In addition to restricted power, mobile devices generally don’t have a hardware root-of-trust and currently lack ubiquitous virtualization capability, which limits some of today’s approaches to security. Even as these security mechanisms reemerge for mobile devices, no single one is expected to be a “silver bullet.” We believe that the need to recharge these mobile devices can be exploited with the introduction of a hygienic smart charger concept. The charger is used to measure, attest, and remediate the integrity of hosted mobile devices via the Universal Serial Bus (USB), while the mobile device re-charges. A reference prototype specifically targeting the Android-based Nexus S is introduced. Keywords-mobile security; measurement and attestation; system integrity; power; hygiene; malware
