Abstract
Some embodiments provide a system that executes a native code module. During operation, the system obtains the native code module. Next, the system loads the native code module into a secure runtime environment. Finally, the system safely executes the native code module in the secure runtime environment by using a set of software fault isolation (SFI) mechanisms that maintain control flow integrity for the native code module and constrain store instructions in the native code module by bounding a valid memory region of the native code module with one or more guard regions.
