Query: Securing Smartphones: A Micro-TCB Approach   As mobile phones have evolved into `smartphones', with complex operating
systems running third- party software, they have become increasingly vulnerable
to malicious applications (malware). We introduce a new design for mitigating
malware attacks against smartphone users, based on a small trusted computing
base module, denoted uTCB. The uTCB manages sensitive data and sensors, and
provides core services to applications, independently of the operating system.
The user invokes uTCB using a simple secure attention key, which is pressed in
order to validate physical possession of the device and authorize a sensitive
action; this protects private information even if the device is infected with
malware. We present a proof-of-concept implementation of uTCB based on ARM's
TrustZone, a secure execution environment increasingly found in smartphones,
and evaluate our implementation using simulations.
