Native Client - A Sandbox for Portable, Untrusted x86 Native Code
Speaker(s) : Brad Chen (Google, Inc)
Native Client is an open-source research technology for running x86 native code in web applications, with the goal of maintaining the browser neutrality, OS portability, and safety that people expect from web apps. Native Client uses software fault isolation and a specialized runtime to direct all system interaction and side effects through managed interfaces. It supports performance-oriented features generally absent from web application programming environments, such as thread support, instruction set extensions such as SSE, and use of compiler intrinsics and hand-coded assembler. We combine these properties in an open architecture designed to leverage existing web standards, and to encourage community review and 3rd-party tools. This technical talk will cover system design and implementation, and some of our experiences securing and using the system.
