Masking mechanism that facilitates safely executing untrusted native code |
摘要 |
This disclosure presents a system that uses masking to safely execute native code. This system includes a processing element that executes the native code and a memory which stores code and data for the processing element. The processing element includes a masking mechanism that masks one or more bits of a target address during a control flow transfer to transfer control to a restricted set of aligned byte boundaries in the native code. |
