Question

How does an emulator program work?

a.

It emulates the behavior of the real dongle’s device driver and fools the protected program into thinking it is communicating with the real dongle.

b.

It divides the program into numerous small chunks that are each encrypted using a different key.

c.

It checks that the dongle is installed by calling into a device driver.

d.

It decrypts the actual program code using the decryption key stored in the dongle.

Answer: (a).It emulates the behavior of the real dongle’s device driver and fools the protected program into thinking it is communicating with the real dongle. Explanation:An emulator program is a device driver that is designed to mimic the behavior of the real dongle’s device driver and fool the protected program into thinking it is communicating with the real dongle when in fact it is communicating with an emulator.
