The task execution code security mechanism in the open cloud computing environment

Cloud computing can fully aggregate the computing resources of Internet network server and edge terminal nodes for greater benefit. However, the deployment of the computing task to the user terminal implementation has brought security risks. The behavior of the massive terminal nodes belonging to different users is obviously unreliable and the computational security is difficult to guarantee. In particular, a user terminal node as a task performer may tamper with the program code or data in a task, return false results, or pry into code and data that has privacy requirements. This paper proposes a new code protection mechanism based on embedded verification code, which can satisfy both computational integrity and privacy, effectively verifies the correctness of return results and guarantees that the computational code is not known. In order to further improve the success rate of task execution and shorten the working turnaround time, the task code is distributed first to the node with good reputation and high execution rate. A method for evaluating the credibility of task execution nodes is also presented. The implementation process of the task execution code protection mechanism is described, and the performance of the mechanism is analyzed and validated in detail.
