Abstract: This disclosure describes systems and methods for protecting commercial off-the-shelf software program code from piracy. A software program may include an executable file. The executable file may include code and data. A platform may modify the executable file such that the data may be placed at a location in memory not based on a fixed distance from the code. The platform may modify the executable file to indicate that the code should be loaded in a hardware enclave and at least a portion of the data should be loaded in the memory outside the hardware enclave. The platform may encrypt the code and provide it to a computing device.

The first negative end and the second negative end have a same potential. The power conversion circuit is configured to convert a first voltage input by a first device into a second voltage and output the second voltage to a second device. The first power terminal is connected to the first positive end, the first negative end or the second negative end is connected to the second power terminal, and the third power terminal is connected to the second positive end.

Abstract: This disclosure describes systems and methods for protecting commercial off-the-shelf software program code from piracy. A software program may include an executable file having code and data. A platform may modify the executable file such that the data may be placed at a location in memory that is an arbitrary distance from the code. The platform may modify the executable file to include a separation header. The separation header may indicate that the data can be placed at an arbitrary distance in the memory from the code. The separation header may indicate that the code should be loaded into a hardware enclave and that the data should be loaded outside of the hardware enclave. The platform may encrypt the code and provide it to a computing device. The computing device may load the encrypted code into the hardware enclave but load the data into memory outside the hardware enclave.
