Device-Centric Monitoring for Mobile Device Management
The ubiquity of computing devices has led to an increased need to ensure not
only that the applications deployed on them are correct with respect to their
specifications, but also that the devices are used in an appropriate manner,
especially in situations where the device is provided by a party other than the
actual user. Much work which has been done on runtime verification for mobile
devices and operating systems is mostly application-centric, resulting in
global, device-centric properties (e.g. the user may not send more than 100
messages per day across all applications) being difficult or impossible to
verify. In this paper we present a device-centric approach to runtime verify
the device behaviour against a device policy with the different applications
acting as independent components contributing to the overall behaviour of the
device. We also present an implementation for Android devices, and evaluate it
on a number of device-centric policies, reporting the empirical results
obtained.Comment: In Proceedings FESCA 2016, arXiv:1603.0837
In-Vivo Bytecode Instrumentation for Improving Privacy on Android Smartphones in Uncertain Environments
In this paper we claim that an efficient and readily applicable means to
improve privacy of Android applications is: 1) to perform runtime monitoring by
instrumenting the application bytecode and 2) in-vivo, i.e. directly on the
smartphone. We present a tool chain to do this and present experimental results
showing that this tool chain can run on smartphones in a reasonable amount of
time and with a realistic effort. Our findings also identify challenges to be
addressed before running powerful runtime monitoring and instrumentations
directly on smartphones. We implemented two use-cases leveraging the tool
chain: BetterPermissions, a fine-grained user centric permission policy system
and AdRemover an advertisement remover. Both prototypes improve the privacy of
Android systems thanks to in-vivo bytecode instrumentation.Comment: ISBN: 978-2-87971-111-
Management system requirements for wireless systems beyond 3G
This paper presents a comprehensive description of various management system requirements for systems beyond 3G, which have been identified as a result of the Software Based Systems activities within the Mobile VCE Core 2 program. Specific requirements for systems beyond 3G are discussed and potential technologies to address them proposed. The analysis has been carried out from network, service and security viewpoints
