170. ZeroKernel: Secure Context-Isolated Execution on Commodity GPUs

Author

Kwon, Ohmin, Kim, Yonggon, Huh, Jaehyuk, and Yoon, Hyunsoo

Abstract

In the last decade, the dedicated graphics processing unit (GPU) has emerged as an architecture for high-performance computing workloads. Recently, researchers have also focused on the isolation property of a dedicated GPU and suggested GPU-based secure computing environments with several promising applications. However, despite the security analysis conducted by the prior studies, it has been unclear whether a dedicated GPU can be leveraged as a secure processor in the presence of a kernel-privileged attacker. In this paper, we first demonstrate the security of dedicated GPUs through comprehensive studies on context information for GPU execution. The paper shows that a kernel-privileged attacker can manipulate the GPU contexts to redirect memory accesses or execute arbitrary GPU codes on the running GPU kernel. Based on the security analysis, this paper proposes a new on-chip execution model for the dedicated GPU and a novel defense mechanism supporting the security of the on-chip execution. With comprehensive evaluation, the paper assures that the proposed solutions effectively isolate sensitive data in on-chip storages and defend against known attack vectors from a privileged attacker, supporting that the commodity GPUs can be leveraged as a secure processor.

Abstract

In the IoT environment, all devices are connected to each other, and mobile device is considered as key device. But hacking into mobile devices is increasing rapidly with the increase in mobile device users. As the market share of Android OS increases, hacking of mobile devices has focused on Android devices. Although there are many security solutions for mobile devices, they are fragmentary for mobile threats; that is, they are solutions for only several threats rather than comprehensive solutions. There is hence a limit to protecting user’s and company’s data stored or used on mobile devices from various types of hacking. To address this, we propose a mobile device protection technology based on domain isolation. Virtualization technology has emerged to increase CPU utilization in server-class PCs and to run various OSs in one system. As these virtualization technologies become lightweight, they are beginning to be applied to embedded devices. In this paper, we applied this lightweight embedded virtualization technology to mobile devices to divide mobile devices into two areas. Therefore, users can have hidden area from hacker attack in addition to Android OS area which can use same as existing mobile device. There is a hardware-based mobile security solution using an secure element, but this has to be reflected in the manufacturing process of the mobile device. However, since the domain separation technology using the virtualization, proposed in this paper, is a software solution, it has an advantage that it can be applied to a device that is already in use. In addition, to protect the hidden area, application authentication/authorization and user authentication technology were applied. And we use white-box cryptography to get root of trust of the key which is used for secure storage and data encryption/decryption. We believe this is a fundamental solution for protecting the mobile device users from hacking. We implemented and tested various mobile applications operating on a mobile device that incorporates our proposed structure based on domain isolation. There is some performance degradation caused by the domain separation, but it is negligible. According to https://www.wired.com/insights/2012/11/mobile-supercomputers/, the chips for mobile phones have evolved and mobile phones will soon become supercomputers. In this case, the addition of virtualization to the mobile device will have less impact on the computing power of the mobile device, and data protection stored in mobile devices and secure execution environment of security programs will become more important issues. Therefore, our TeeMo structure is a necessary technology to protect mobile device users. [ABSTRACT FROM AUTHOR]
