CSR: Medium: A Virtual Smartphone and Tablet System Architecture

智能手机越来越普遍。许多用户被迫携带多部智能手机以满足工作、个人和地理移动需求。这项研究正在开发 Cells，这是一种轻量级虚拟化架构，使多个虚拟智能手机能够以安全隔离的方式在同一物理设备上同时运行。 Cells 引入了新的设备命名空间机制和新颖的设备代理，可以跨多个虚拟电话高效、安全地多路复用电话硬件设备，同时为所有应用程序提供本机硬件设备性能​​。虚拟电话功能包括完全加速的游戏图形、完整的电源管理功能、易于使用的安全机制（可以透明、动态地控制电话功能的可用性）以及具有可单独分配的电话号码和来电显示支持的完整电话功能。 Cells 在使用最广泛的智能手机平台 Android 中实现，可在同一手机硬件上透明地支持多个 Android 虚拟手机。虽然这项研究的主要焦点是智能手机设备，但这些想法的发展也在平板电脑设备的背景下进行了探索。这项研究的结果为智能手机计算的未来创新奠定了基础，实现了新的用途和应用，并改变了设备的使用方式。这项研究不仅有望提高系统安全性，还能提高用户安全性；特别是对于年轻人来说。将这项研究与计算机科学课程相结合，为学生提供了通过智能手机设备上的编程项目进行实践学习的机会，使他们能够随着智能手机成为日益占主导地位的计算平台而成为劳动力的贡献者。

Smartphones are increasingly ubiquitous. Many users are forced to carry multiple smartphones for work, personal, and geographic mobility needs. This research is developing Cells, a lightweight virtualization architecture for enabling multiple virtual smartphones to run simultaneously on the same physical device in a securely isolated manner. Cells introduces a new device namespace mechanism and novel device proxies that multiplex phone hardware devices efficiently and securely across multiple virtual phones while providing native hardware device performance to all applications. Virtual phone features include fully accelerated graphics for gaming, complete power management features, easy-to-use security and safety mechanisms that can control the availability of phone features transparently and dynamically, and full telephony functionality with separately assignable telephone numbers and caller ID support. Cells is implemented in Android, the most widely used smartphone platform, to transparently support multiple Android virtual phones on the same phone hardware. While the primary focus of this research is smartphone devices, the development of these ideas is also explored in the context of tablet devices. The results of this research provide a foundation for future innovations in smartphone computing, enabling new uses and applications and transforming the way the devices can be used. This research promises to improve not just system security, but also user safety; especially for young people. Integrating this research with the CS curriculum provides students with hands-on learning through programming projects on smartphone devices, enabling them to become contributors to the workforce as smartphones become an increasingly dominant computing platform.
