Encoded Function Execution for Secure Distributed Code Running

The patent introduces an intermediary layer (interpreter or virtual machine) between the downloaded code and the execution device's native code executor. This intermediary translates and executes code in a controlled environment, maintaining execution speed while preventing arbitrary program execution and security breaches.

The patent creates a virtual copy of the execution environment through a virtual machine or sandbox. Code is executed in this isolated copy rather than directly on the host system, enabling fast native code execution while containing security risks within the virtual environment.

The patent performs preliminary static validation of code before execution to establish a baseline security state. Additionally, it implements runtime monitoring that continuously verifies code integrity during execution, detecting injections that occur after the preliminary check.

The patent implements a feedback mechanism where the execution monitor continuously checks code integrity during runtime and provides feedback to the security system. When code injection is detected, the system can terminate execution or alert the user, addressing the limitation of static validation alone.

The patent implements a dynamic execution system that adapts the interpretation method based on code characteristics and security requirements. For trusted code, it uses faster execution methods, while for untrusted code, it applies stricter interpretation, optimizing both security and performance.

The patent segments code execution into different phases with different interpretation strictness. Critical security-related code is executed with full interpretation and validation, while non-critical code can use optimized execution paths, balancing security requirements with performance needs.
