ABSTRACT:
A system and method in which the operating system of the user computer loads the software application and a DLL having a portion of the application execution code stored therein into memory is disclosed. At selected points during its execution, the software application calls the DLL to execute a portion of the application code that was saved into the DLL before delivery to the end user. Since this code is encrypted and the encryption key is stored in a hardware security device and not in the DLL or the software application, the application code portion cannot be executed without recovering the key.
