Sensitive data protection is essential for mobile users. Plausibly DeniableEncryption (PDE) systems provide an effective manner to protect sensitive databy hiding them on the device. However, existing PDE systems can lose data dueto overriding the hidden volume, waste physical storage because of the reservedarea used for avoiding data loss, and require device reboot when using thehidden volume. This paper presents MobiGyges, a hidden volume-based mobile PDEsystem, to fill the gap. MobiGyges addresses the problem of data loss byrestricting each storage block used only by one volume, and it improves storageutilization by eliminating the reserved area. MobiGyges can also avoid devicereboot by mounting the hidden volume dynamically on-demand with the DynamicMounting service. Moreover, we identify two novel PDE oriented attacks, thecapacity comparison attack and the fill-to-full attack. MobiGyges can defendthem by jointly leveraging the Shrunk U-disk method and multi-leveldeniability. We implement the MobiGyges proof-of-concept system on a realmobile phone Google Nexus 6P with LineageOS 13. Experimental results show thatMobiGyges prevents data loss, avoids device reboot, improves storageutilization by over 30% with acceptable performance overhead compared withcurrent works.
