Abstract
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for processing just-in-time code at a device that enforces a code signing requirement. The disclosure includes receiving computer code, where a portion of the code includes executable just-in-time code, at a device that enforces a code signing requirement; identifying the unsigned just-in-time executable portion of code; allocating a randomly selected memory region on the device for at least some of the unsigned just-in-time executable portion; and executing the unsigned just-in-time executable portion of code in the randomly selected memory region as if the unsigned just-in-time executable portion of code was signed computer code.
