摘要

This invention is the system and the manner which verify the genuine Characteristic of feasibility image. This system the part of the feasibility format which is prepared by the program loader using the contents of the digitalized signature which is not included, possesses the execution time verification section which decides the contrast digitalized signature for feasibility format. The execution time verification section, following to the loading of feasibility image, in order to verify that feasibility image is not adjusted to inadequacy decides genuine digitalized signature. Furthermore, the execution time verification section guarantees that each pointer which is while feasibility representing has not been rewritten ahead specifying to inadequacy.
