Abstract
Official abstract text for this publication.
The present invention provides an execution method of a .NET program after encryption. An operating system allocates a process address space to a .NET program process and maps PE files into the process address space respectively. After the .NET program process runs, it is judged whether a currently running program module is encrypted. The .NET program process continues to run after the encrypted program module is decrypted. If the current program module calls a subroutine module, it is judged whether the subroutine module is encrypted. If the subroutine module is encrypted, a decryption operation is performed, and the .NET program process continues to run. With the method, encryption management can be performed on the .NET program based on modules, thereby providing diversified functions for protecting .NET software.
First claim
Opening claim text (preview).
The invention claimed is: 1. An execution method of .NET program after encryption, characterized in that said method comprises: loading an HOOK engine and a .NET kernel, starting a .NET process, and beginning to run a .NET program module by an operating system; determining, by the HOOK engine, whether a current program module is encrypted; invoking, by the HOOK engine, a decryption module to decrypt the current program module, if the current program module is encrypted; comp…
