In this paper, we present MobiPluto, a file system friendly PDE scheme for denying the existence of sensitive data stored on mobile devices.  ...  A salient di↵erence between MobiPluto and the existing PDE schemes is that MobiPluto is "file system friendly", i.e., any block-based file systems can be deployed on top of it.  ...  ACKNOWLEDGMENTS We would like to thank our shepherd, Ariel Feldman, and anonymous ACSAC reviewers for their insightful suggestions and advice.  ...

In this paper, we present MobiPluto, a user-friendly PDE scheme for denying the existence of sensitive data stored on mobile devices.  ...  A salient difference between MobiPluto and the existing PDE systems is that any block-based file systems can be deployed on top of it.  ...  Compared to TrueCrypt, MobiPluto decouples file system from the underlying storage medium, achieving file-system-friendly feature.  ...

Towards Designing A Secure Plausibly Deniable System for Mobile Devices against Multi-snapshot Adversaries – A Preliminary Design [article]

Bo Chen
2020 arXiv   pre-print
Leveraging concept of PDE, various deniable storage systems have been built for both PC and mobile platforms.  ...  In this work, we propose a preliminary PDE system design for mobile computing devices using flash memory as underlying storage medium.  ...  Acknowledgment We would like to thank Fengwei Zhang for the initial discussion of the design during 2018.  ...

The Block-based Mobile PDE Systems Are Not Secure – Experimental Attacks [article]

Niusen Chen, Bo Chen, Weisong Shi
2022 arXiv   pre-print
However, most of the existing PDE systems for mobile devices are deployed at the block layer and suffer from deniability compromises.  ...  We have built a mobile device testbed, which consists of a host computing device and a flash storage device.  ...  [32] proposed DEFY, the first deniable file system designed for log-structured storage.

Ensuring data confidentiality via plausibly deniable encryption and secure deletion – a survey

Qionglu Zhang, Shijie Jia, Bing Chang, Bo Chen
2018 Cybersecurity  
Especially for encryption, we mainly focus on the novel plausibly deniable encryption (PDE), which can ensure data confidentiality against both a coercive (i.e., the attacker can coerce the data owner  ...  for the decryption key) and a non-coercive attacker.  ...  By combining thin provisioning and hidden volumes, MobiPluto is able to achieve a "file system friendly" PDE design.  ...

MobiGyges: A mobile hidden volume for preventing data loss, improving storage utilization, and avoiding device reboot

Wendi Feng, Chuanchang Liu, Zehua Guo, Thar Baker, Gang Wang, Meng Wang, Bo Cheng, Junliang Chen
2020 Future generations computer systems  
Sensitive data protection is essential for mobile users. Plausibly Deniable Encryption (PDE) systems provide an effective manner to protect sensitive data by hiding them on the device.  ...  However, existing PDE systems can lose data due to overriding the hidden volume, waste physical storage because of the reserved area used for avoiding data loss, and require device reboot when using the  ...  We would also like to thank the editors and anonymous reviewers for their valuable comments and suggestions.  ...

SoK: Plausibly Deniable Storage

Chen Chen, Xiao Liang, Bogdan Carbunar, Radu Sion
2022 Proceedings on Privacy Enhancing Technologies  
Popular encrypted storage systems such as TrueCrypt and other research efforts have attempted to also provide plausible deniability.  ...  This work is meant also as a trusted guide for system and security practitioners around the major challenges in understanding, designing and implementing plausible deniability into new or existing systems  ...  Acknowledgements We thank the shepherd, Diogo Barradas, and the anonymous reviewers for their feedback.  ...
