The proliferating numbers of smartphone
applications which access device’s
functionalities and resources such as GPS, SMS
etc imposes security challenges. In the meantime,
the existing security and access control
mechanism of smartphone mostly hold a coarsegrained
and incomplete access control model.
This paper proposes a fine-grained access
control; a context-related access control
mechanism for Android smartphone platform.
Exploiting the current behavior of system and
user as well as their interaction, the proposed
system enables access control to be made not
only at install-time but also at runtime.
Moreover, users can impose security policies to
their device usage without requiring technical
knowledge. By using simple policy and context,
the system fulfills necessity of existing access
control mechanism within minimum performance
overhead. |
