摘要
The present invention provides a method and system for runtime code integrity validation. The method and system include providing a software tool for processing a software program, as well as instructions on how to modify the software program for submission to the tool. The modified software program executable generated for submission to the tool includes checksum information for use by the tool. The tool uses the checksum information to compute checksums on blocks specified by the checksum information, and stores the computed checksums in locations specified by the checksum information. Next, the tool strips the checksum information from the executable. The resulting executable code is delivered as a protected software application that generates a new checksum at runtime and compares it with the computed checksum, and determines that the software program has been modified if the checksums fail to match.
